Richard Eric Parry Winpenny FRSC FLSW is a British chemist and a professor in the Department of Chemistry at the University of Manchester. [1] Winpenny's research is within the fields of inorganic chemistry and magnetochemistry, specifically the areas of single-molecule magnetism, inorganic synthesis, supramolecular chemistry and polymetallic caged complexes. [8]
Winpenny was educated at Sandfields Comprehensive School, Port Talbot, where he was influenced by his excellent chemistry teachers, John Hardie and Vivien Davies, to study chemistry at university. [9] He thus completed both his Bachelor of Science and Doctor of Philosophy degree at Imperial College London in 1985 and 1988 respectively. [9] His PhD on New heterometallic polynuclear complexes was supervised by David Goodgame. [9] [10]
Upon completing his PhD, Winpenny completed his postdoctoral research with John Fackler, Jr at Texas A&M University from 1988 to 1989 where he researched on mass spectrometry of gold clusters. [1] In 1990, he joined the University of Edinburgh as an academic, and in 2000, moved to The University of Manchester as the chair of inorganic chemistry. [9]
Winpenny was the Associate Dean for Research in the University of Manchester Faculty of Science and Engineering from September 2008 to April 2010. [9] He was also the director of the Photon Science Institute from October 2009 to April 2014. [11] Winpenny was also the head of the Department of Chemistry at the University of Manchester from August 2014 to April 2018, and is the director and chief scientific officer at Sci-Tron(Ltd.). [9] He was also awarded Engineering and Physical Sciences Research Council (EPSRC) Established Career Fellowship (January 2018 to December 2022) and also holds a European Research Council Advanced Fellowship from September 2018 to August 2022. [12]
Winpenny is classed as one of the leading synthetic chemists of polymetallic cage complexes. [6] He has developed a wide range of heterometallic rings as a new class of molecular magnets, [6] which have been exploited to develop new physics and techniques with proposals to use them in quantum information processing. These rings also show unique capabilities to act as resist materials for electron beam lithography (EBL).
A wide range of literature has been published by Winpenny on the synthesis, structural and property analysis of heterometallic rings, polymetallic cages, single molecule magnets, and f-block and d-block metal complexes. [13] [14] [15] The published work by Winpenny has gained more than 24,000 citations as of 2020. [8]
In 2007, Winpenny also reported the first intrinsic spin-lattice (T1) and phasecoherence (T2) relaxation times in molecular nanomagnets. The results showed that the value of T2 in deuterated samples were of several orders of magnitude longer than the duration of spin manipulations which satisfies the prerequisite for the deployment of molecular nanomagnets in quantum information applications. [16]
In 2016, a research led by Winpenny, Nicholas F. Chilton and Yan‐Zhen Zheng was able to report a monometallic dysprosium complex which showed the largest effective energy barrier to magnetic relaxation of Ueff = 1815 K. [17] The research also showed the largest blocking temperature (TB) for a monometallic complex.
William Nunn Lipscomb Jr. was a Nobel Prize-winning American inorganic and organic chemist working in nuclear magnetic resonance, theoretical chemistry, boron chemistry, and biochemistry.
Intersystem crossing (ISC) is an isoenergetic radiationless process involving a transition between the two electronic states with different spin multiplicity.
Valence shell electron pair repulsion (VSEPR) theory, is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. It is also named the Gillespie-Nyholm theory after its two main developers, Ronald Gillespie and Ronald Nyholm.
Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic nuclei. This spectroscopy is based on the measurement of absorption of electromagnetic radiations in the radio frequency region from roughly 4 to 900 MHz. Absorption of radio waves in the presence of magnetic field is accompanied by a special type of nuclear transition, and for this reason, such type of spectroscopy is known as Nuclear Magnetic Resonance Spectroscopy. The sample is placed in a magnetic field and the NMR signal is produced by excitation of the nuclei sample with radio waves into nuclear magnetic resonance, which is detected with sensitive radio receivers. The intramolecular magnetic field around an atom in a molecule changes the resonance frequency, thus giving access to details of the electronic structure of a molecule and its individual functional groups. As the fields are unique or highly characteristic to individual compounds, in modern organic chemistry practice, NMR spectroscopy is the definitive method to identify monomolecular organic compounds.
A single-molecule magnet (SMM) is a metal-organic compound that has superparamagnetic behavior below a certain blocking temperature at the molecular scale. In this temperature range, a SMM exhibits magnetic hysteresis of purely molecular origin. In contrast to conventional bulk magnets and molecule-based magnets, collective long-range magnetic ordering of magnetic moments is not necessary.
In chemistry, a pentagonal bipyramid is a molecular geometry with one atom at the centre with seven ligands at the corners of a pentagonal bipyramid. A perfect pentagonal bipyramid belongs to the molecular point group D5h.
In magnetism, a nanomagnet is a nanoscopic scale system that presents spontaneous magnetic order (magnetization) at zero applied magnetic field (remanence).
