Jacqueline Manina Cole is the Head of the Molecular Engineering group in the Cavendish Laboratory at the University of Cambridge. Her research considers the design of functional materials for optoelectronic applications. [2]
Cole earned her first degree in chemistry at Durham University in 1994. She remained there for her graduate studies, completing a PhD in 1997 (Grey College). [3] Her thesis, Structural studies of organic and organometallic compounds using x-ray and neutron techniques, described the structure-property relationships of non-linear optical materials, including studies of transition metal complexes. [4] [5] She was supervised by Judith Howard. [4]
Cole was appointed a postdoctoral research associate at the University of Kent, where she worked on the structure of amorphous materials. [6] Cole moved to the University of Cambridge as a Junior Research Fellow in St Catharine's College, Cambridge in 2001. [7] Here she began to investigate photo-crystallography. In her spare time, Cole completed a bachelor's degree in mathematics at the Open University. After the bachelor's degree in mathematics, Cole earned diplomas in statistics (2004), physics (2008) and astronomy (2006) as well as a second bachelor's degree in engineering (2014) from the Open University. Cole earned a second doctorate in physics at the University of Cambridge in 2010. [8]
As a Royal Society University Research Fellow, [1] Cole developed a new analytical approach to establish the photo-induced structures of optoelectronic materials. [6] Photo-crystallography permits the 4D structural determination of photo-activated states. [6] [9] Photo-activation can result in structural changes that are irreversible, reversible, long-lived (microsecond lifetimes) and very short-lived (nanosecond lifetimes). [6] Cole uses single-crystal X-ray crystallography to monitor the minute structural changes that occur during photo-excitation. [6] Photo-crystallography allows the visualisation of switching processes in single crystals. [10] In 2008 she was appointed Vice-Chancellor's Research Chair at the University of New Brunswick. [11]
Cole is interested in dye-sensitized solar cells, nonlinear optics and optical data storage. [2] [11] In dye-sensitized solar cells, the dye absorbs sunlight, injecting electrons into titanium dioxide nanoparticles and starting an electric circuit. Cole worked on the design of organic fluorophores in an effort to improve the performance of the dye. [12] [13] She investigated how data mining and Quantum chemical calculations could be used to predict which dyes might perform best. [14] She uses the EPSRC National Service for Computational Chemistry Software. [15] She has looked to use some of the dyes, in particular p-phenylene, as a laser. [16]
Whilst inorganic materials dominate the photonic device industry, the need for high-speed telecommunications has exceed their limitations. Organic electronic materials have a significantly faster response time. [15] Whilst working at the Argonne National Laboratory, Cole used in situ neutron reflectometry to study the interaction between the electrolytes and electrodes in dye-sensitized solar cells. [17] She designed cells that used metal-free organic dyes and achieve a 14.3% efficiency. [17] [18] [19] The cells incorporated an organic sensitiser, MK-44, and an organic dye, MK-2, based on thiophenylcyanoacrylate. [20] Cole optimised the anchoring characteristics of the dye on titanium dioxide nanoparticles to improve charge-transfer pathways. [20] [21]
Her early work considered how molecular structure impacted second-harmonic generation. [22] Cole studied the origins of the nonlinear optics observed in N-methylurea, where solid-state intermolecular interactions and electron-donation from the methyl group separate it from the reference material urea. [23] She has investigated the molecular design rules of organometallic second-harmonic generation active materials. [24]
In 2018 Cole was appointed a Royal Academy of Engineering Senior Research Fellow. [25] The fellowship is a collaboration between the Science and Technology Facilities Council (STFC), BASF and ISIS neutron source to discover functional materials systematically. [26] As of 2019, Cole leads the Molecular Engineering group in the Cavendish Laboratory. [6] She works with the Rutherford Appleton Laboratory on data science and buried interfaces. She has recently designed new databases of magnetic materials. [27]
Molecular engineering is an emerging field of study concerned with the design and testing of molecular properties, behavior and interactions in order to assemble better materials, systems, and processes for specific functions. This approach, in which observable properties of a macroscopic system are influenced by direct alteration of a molecular structure, falls into the broader category of “bottom-up” design.
A dye-sensitized solar cell is a low-cost solar cell belonging to the group of thin film solar cells. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. The modern version of a dye solar cell, also known as the Grätzel cell, was originally co-invented in 1988 by Brian O'Regan and Michael Grätzel at UC Berkeley and this work was later developed by the aforementioned scientists at the École Polytechnique Fédérale de Lausanne (EPFL) until the publication of the first high efficiency DSSC in 1991. Michael Grätzel has been awarded the 2010 Millennium Technology Prize for this invention.
In chemistry, triiodide usually refers to the triiodide ion, I−
3. This anion, one of the polyhalogen ions, is composed of three iodine atoms. It is formed by combining aqueous solutions of iodide salts and iodine. Some salts of the anion have been isolated, including thallium(I) triiodide (Tl+[I3]−) and ammonium triiodide ([NH4]+[I3]−). Triiodide is observed to be a red colour in solution.
Perylene or perilene is a polycyclic aromatic hydrocarbon with the chemical formula C20H12, occurring as a brown solid. It or its derivatives may be carcinogenic, and it is considered to be a hazardous pollutant. In cell membrane cytochemistry, perylene is used as a fluorescent lipid probe. It is the parent compound of a class of rylene dyes.
Photosensitizers are light absorbers that alter the course of a photochemical reaction. They usually are catalysts. They can function by many mechanisms, sometimes they donate an electron to the substrate, sometimes they abstract a hydrogen atom from the substrate. At the end of this process, the photosensitizer returns to its ground state, where it remains chemically intact, poised to absorb more light. One branch of chemistry which frequently utilizes photosensitizers is polymer chemistry, using photosensitizers in reactions such as photopolymerization, photocrosslinking, and photodegradation. Photosensitizers are also used to generate prolonged excited electronic states in organic molecules with uses in photocatalysis, photon upconversion and photodynamic therapy. Generally, photosensitizers absorb electromagnetic radiation consisting of infrared radiation, visible light radiation, and ultraviolet radiation and transfer absorbed energy into neighboring molecules. This absorption of light is made possible by photosensitizers' large de-localized π-systems, which lowers the energy of HOMO and LUMO orbitals to promote photoexcitation. While many photosensitizers are organic or organometallic compounds, there are also examples of using semiconductor quantum dots as photosensitizers.
Hybrid solar cells combine advantages of both organic and inorganic semiconductors. Hybrid photovoltaics have organic materials that consist of conjugated polymers that absorb light as the donor and transport holes. Inorganic materials in hybrid cells are used as the acceptor and electron transporter in the structure. The hybrid photovoltaic devices have a potential for not only low-cost by roll-to-roll processing but also for scalable solar power conversion.
A photoswitch is a type of molecule that can change its structural geometry and chemical properties upon irradiation with electromagnetic radiation. Although often used interchangeably with the term molecular machine, a switch does not perform work upon a change in its shape whereas a machine does. However, photochromic compounds are the necessary building blocks for light driven molecular motors and machines. Upon irradiation with light, photoisomerization about double bonds in the molecule can lead to changes in the cis- or trans- configuration. These photochromic molecules are being considered for a range of applications.
Michael Grätzel is a professor at the École Polytechnique Fédérale de Lausanne where he directs the Laboratory of Photonics and Interfaces. He pioneered research on energy and electron transfer reactions in mesoscopic-materials and their optoelectronic applications. He co-invented with Brian O'Regan the Grätzel cell in 1988.
An organic solar cell (OSC) or plastic solar cell is a type of photovoltaic that uses organic electronics, a branch of electronics that deals with conductive organic polymers or small organic molecules, for light absorption and charge transport to produce electricity from sunlight by the photovoltaic effect. Most organic photovoltaic cells are polymer solar cells.

Yellowlees was also elected as the president of the Royal Society of Chemistry 2012–14 and was the first woman to hold that role.
A perovskite solar cell (PSC) is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic–inorganic lead or tin halide-based material as the light-harvesting active layer. Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture.

Diketopyrrolopyrroles (DPPs) are organic dyes and pigments based on the heterocyclic dilactam 2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione, widely used in optoelectronics. DPPs were initially used as pigments in the painting industry due to their high resistance to photodegradation. More recently, DPP derivatives have been also investigated as promising fluorescent dyes for bioimaging applications, as well as components of materials for use in organic electronics.
James Robert DurrantFRSC FLSW is a British photochemist. He is a professor of photochemistry at Imperial College London and Sêr Cymru Solar Professor at Swansea University. He serves as director of the centre for plastic electronics (CPE).
Triplet-triplet annihilation (TTA) is an energy transfer mechanism where two molecules in their triplet excited states interact to form a ground state molecule and an excited molecule in its singlet state. This mechanism is example of Dexter energy transfer mechanism. In triplet-triplet annihilation, one molecule transfers its excited state energy to the second molecule, resulting in the first molecule returning to its ground state and the second molecule being promoted to a higher excited singlet state.
Light harvesting materials harvest solar energy that can then be converted into chemical energy through photochemical processes. Synthetic light harvesting materials are inspired by photosynthetic biological systems such as light harvesting complexes and pigments that are present in plants and some photosynthetic bacteria. The dynamic and efficient antenna complexes that are present in photosynthetic organisms has inspired the design of synthetic light harvesting materials that mimic light harvesting machinery in biological systems. Examples of synthetic light harvesting materials are dendrimers, porphyrin arrays and assemblies, organic gels, biosynthetic and synthetic peptides, organic-inorganic hybrid materials, and semiconductor materials. Synthetic and biosynthetic light harvesting materials have applications in photovoltaics, photocatalysis, and photopolymerization.
