Overview

Our research involves the synthesis of compounds, supermolecular assemblies, nano-scale objects, and electronic materials with unusual ground-and excited-state characteristics, and interrogating these structures using state-of-the-art transient optical, spectroscopic, photophysical, and electrochemical methods. Research activities span physical inorganic chemistry, physical organic chemistry, synthetic chemistry, bioinorganic chemistry, spectroscopy, photophysics, excited-state dynamics, spintronics, and imaging. My laboratory: (i) designs chromophores and supermolecules that display exceptional opto-electronic properties and elucidates their excited-state dynamics, (ii) engineers highly conjugated molecular structures for optical limiting, specialized emission, and high charge mobility, (iii) designs conjugated materials and hybrid molecular-nanoscale structures for energy conversion reactions, (iv) develops molecular wires that propagate spin-polarized currents, (v) fabricates emissive nanoscale structures for in vivo optical imaging, (vi) engineers de novo transition metal cofactor-binding proteins that test light-driven biological energy transducing mechanisms and realize opto-electronic functionalities not found in nature, and (vii) designs and interrogates complex molecular and nanoscale assemblies in which ultrafast energy and charge migration reactions are controlled by quantum coherence effects.
