Malika Jeffries-EL is an American chemist and professor of chemistry at Boston University studying organic semiconductors. [1] Specifically, her research focuses on developing organic semiconductors that take advantage of the processing power of polymers and the electronic properties of semiconductors to create innovative electronic devices. [3] She was elected as a Fellow of the American Chemical Society in 2018. [4]
Jeffries-EL is from Brooklyn, New York and was the first in her immediate family to attend college. [5] She was inspired to become a scientist by Mae Jemison, an American engineer, physicist, and astronaut who was the first black woman to travel to space. [6] Jeffries-EL earned BA degrees in Chemistry and Africana Studies from Wellesley College in 1996. [5] [7] In 1999 she earned her master's degree in chemistry from George Washington University (GWU). In 2002, Jeffries-EL completed her PhD in Synthetic Chemistry at GWU. Richard Tarkka supervised her. [2] [7] [8]
After completing her PhD, Jeffries-EL worked as a postdoctoral fellow at Carnegie Mellon University under the supervision of Richard D. McCullough from 2002 to 2005. [4] While there, she worked on the synthesis and field-effect mobility of polythiophene. [9] [10] In 2005, she joined the faculty at Iowa State University and was promoted to tenure in 2012. [11] [12] Jeffries-EL works on organic semiconductors. [13] [14]
Jeffries-EL served as a Martin Luther King visiting professor at Massachusetts Institute of Technology between 2014 and 2015. [15] [16] [17] Here, her group focused on the synthesis of polymer building blocks, including heterocyclic electron-rich (donor) and electron-poor (acceptor) units. [18] [19] For electron-deficient units, Jeffries-EL develops benzobisazoles. [20] [21] She is interested in cross-conjugated organic semiconductors, including benzodifurans, as well as functional Polythiophenes. [22] [23] She uses the materials for organic solar cells, transistors and light-emitting diodes. [24]
In 2015 Jeffries-EL was selected as the 8th Annual Goldstein Distinguished Lecturer by Cal Poly Pomona College of Engineering. [25] She was the keynote speaker at the 2016 Northeastern Section of the American Chemical Society meeting. [26]
In 2016 she joined Boston University as a tenured associate professor. [27]
Jeffries-EL has nearly 100 publications. [1] Some of her notable/highly cited publications include the following:
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure determines their structural formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical study.
Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The main advantage of conductive polymers is that they are easy to process, mainly by dispersion. Conductive polymers are generally not thermoplastics, i.e., they are not thermoformable. But, like insulating polymers, they are organic materials. They can offer high electrical conductivity but do not show similar mechanical properties to other commercially available polymers. The electrical properties can be fine-tuned using the methods of organic synthesis and by advanced dispersion techniques.
Polythiophenes (PTs) are polymerized thiophenes, a sulfur heterocycle. The parent PT is an insoluble colored solid with the formula (C4H2S)n. The rings are linked through the 2- and 5-positions. Poly(alkylthiophene)s have alkyl substituents at the 3- or 4-position(s). They are also colored solids, but tend to be soluble in organic solvents.
Polypyrrole (PPy) is an organic polymer obtained by oxidative polymerization of pyrrole. It is a solid with the formula H(C4H2NH)nH. It is an intrinsically conducting polymer, used in electronics, optical, biological and medical fields.
Jean M.J. Fréchet is a French-American chemist and professor emeritus at the University of California, Berkeley. He is best known for his work on polymers including polymer-supported chemistry, chemically amplified photoresists, dendrimers, macroporous separation media, and polymers for therapeutics. Ranked among the top 10 chemists in 2021, he has authored nearly 900 scientific paper and 200 patents including 96 US patents. His research areas include organic synthesis and polymer chemistry applied to nanoscience and nanotechnology with emphasis on the design, fundamental understanding, synthesis, and applications of functional macromolecules.
Pentacene is a polycyclic aromatic hydrocarbon consisting of five linearly-fused benzene rings. This highly conjugated compound is an organic semiconductor. The compound generates excitons upon absorption of ultra-violet (UV) or visible light; this makes it very sensitive to oxidation. For this reason, this compound, which is a purple powder, slowly degrades upon exposure to air and light.
Omar M. Yaghi is the James and Neeltje Tretter Chair Professor of Chemistry at the University of California, Berkeley, an affiliate scientist at Lawrence Berkeley National Laboratory, the Founding Director of the Berkeley Global Science Institute, and an elected member of the US National Academy of Sciences as well as the German National Academy of Sciences Leopoldina.
