Arumugasamy Elangovan, Ph.D.
Department of Chemistry, University of Washington, Seattle 98195-1700
Current position : Acting Instructor
Responsibilities: Providing day-to-day leadership and assisting Professor
Larry R. Dalton in mentoring a diverse group of graduate students,
undergraduates, and postdoctoral scientists. Conducting research on
the design, synthesis
and development of new organic NLO chromophores with high electo-optic
Current Classes (Winter 2009): CHEM 241AH and 241 AQ (CHB 128 - T, Th; and CHB 111 - W, F)
Current interest: Design and development of novel organic molecules useful as materials in electronics, telecommunication and information technology.
Strategy: Exploitation of the ability of organic molecules to interact with, and respond to light and electric field.
Design approach starts with the use of theoretical modeling involving, in addition to other models, Density Functional Theory as the major tool for the design of molecules to predict the various properties such as energy, dipole, molecular orbital energy levels, molecular polarizabilities and hyperpolarizabilities – properties of molecules that get altered in response towards external stimuli such as electromagnetic radiations and electric field.
Translation of the molecular properties into bulk properties lies in the ability to realize the synthesis of materials and use them for application in devices such as electro-optic modulators, optical limiters, in biological analysis and as data storage devices. Intensive research efforts are under way to realize material syntheses in several grams scale.
General research interests: Organic photonics; Optoelectronic materials; Molecular electronics; Macromolecules and Supramolecular Chemistry; Host-Guest Chemistry; Liquid Crystals; OLED. Design and development of new catalysts, reactions, techniques and methodology; Structurally novel organic molecules; Synthesis and study of photophysical properties of donor-acceptor ethenes, ethynes, eneynes and diynes; Nanoscience and Technology; Fullerene and Carbon Nanotube Chemistry; Self Assembly.
