Designing new organic materials with electronic, optical, and magnetic properties

Our research aims to develop novel conductive organic materials for optoelectronic and biomedical applications. Specifically, we synthesize new π-conjugated organic molecules/polymers and characterize their optoelectronic and magnetic properties. Our work combines organic synthesis, polymer chemistry, materials science, and nanomedicine.

 

Ongoing projects include, but not limited to: 

(1) organic n-type semiconductors
(2) organic π-radical conductors
(3) exotic organic superconductors

 

project1Organic n-type semiconductors. We are designing and synthesizing novel electron-deficient π-conjugated structures and measuring their charge mobilities in organic field-effect transistors. We are also investigating new postpolymerization strategies for synthesizing these organic n-type semiconducting structures. Interdisciplinary collaborations in the area of organic bioelectronics are anticipated.

 

project2Organic π-radical conductors. Organic structures with unpaired electrons often display unique properties such as intrinsic electrical conductivity and nonlinear optical behavior. However, practical applications remain challenging due to their highly reactive nature. Our goal here is to design and synthesize stable radical-based systems with properties that are useful for microelectronics and bio-imaging.

 

project3Organic superconductors. Superconductivity is a macroscopic quantum phenomenon more commonly observed in inorganic materials than in organic ones. We are exploring novel and unusual organic structures in an effort to push the limits of superconducting critical temperatures (Tc). The discovery of new superconductors that work at practical temperatures will have major impacts on many technologies, e.g. electronics, energy, health care, and transportation.
