Prof. Deqing ZHANG studied chemistry at Beijing Normal University from 1983 to 1987. He then joined in the Institute of Chemistry, Chinese Academy of Sciences (ICCAS) as a graduate student and obtained his MS. in Organic Chemistry in 1990. He conducted research on electron donor–acceptor cyclophenes at the Max-Planck Institute for Medical Research in Heidelberg (Germany) under the supervision of Prof. Dr H. A. Staab, and received his Doctor degree (DR. RER. NAT.) from Ruprecht-Karls University Heidelberg in 1996. He is now a Professor in the Institute of Chemistry, CAS. His research mainly focuses on the design and synthesis of new conjugated molecules and polymers for organic optoelectronic materials. He also show interests on external stimuli responsive molecules and supramolecules for molecular switches, logic gates and chemical sensors. He has published more than 360 papers in international refereed journals. He serves as co-editor of ACS Omega, and editorial advisory board or international advisory board members of Acc. Chem.

High Performance Polymer Semiconductors via Side Chain Functionalization/ format references

Abstract

Semiconducting polymers with alternating donor and acceptor units in the backbones have been intensively investigated for the past decades. The applications of polymer semiconductors in field-effect transistors (FETs), inverters, memory devices and sensors have been successfully demonstrated. Currently, high performance polymer semiconductors are highly demanding for flexible electronics. Conjugated polymers with different backbones were explored aiming to enhance charge mobilities. Meanwhile, photo-tunable polymer semiconductors have received increasing attentions in recent years because they are inevitably needed for multi-functional devices. Furthermore, controllable photo-patterning of polymer semiconductors is the key step for device integration. In this presentation, I will discuss our recent works on boosting charge mobility, tuning the semiconducting performance, and achieving photo-patterning for conjugated D-A polymers by modification of side alkyl chains and incorporation of functional groups.
