Welcome to Yi Pang’s Research Group at University of Akron

Department of Chemistry & Maurice Morton Institute of Polymer Science

Our research laboratory seeks design and synthesis of novel p-conjugated materials that has potential applications in material science and chemical sensors.  One current area is to modify the interaction at the surface of carbon nanotube (CNT), with the goal to isolate CNT of specific chirality.  In another direction, we are interested in understanding the fundamental impact of chemical structures and nano assembly on the luminescent properties of p-conjugated materials. The study aims to develop new materials that can specifically recognize the chemical species of biological importance (e.g. Zn2+, proteins, ATP, pyrophosphate).

Research Position:  Our group is focusing on developing luminescent materials for a broad range of applications.  Motivated graduate students or researchers are encouraged to contact Dr. Yi Pang (phone:330-972-8263, or email: yp5@uakron.edu).
