Organic Polymers and Their Composites for Electronic and Thermoelectric Application
劉振良 教授
摘要 :
Organic semiconductors have attracted much attention for their potential applications and commercial products such as organic light-emitting diode (OLED) displays, organic field effect transistors (OFETs)-based active matrix display, and organic-based radio frequency identification (RFID) tags, Among these, solution-processable small molecules with high performance and ambient stability are of great interest due to their possibility of a low-cost solution process and high flexibility in molecular design/modification for various electronic/thermoelectric applications. In my talk, we outline the design strategies which aim to develop high performing organic semiconductor materials in the fields of OFETs and organic thermoelectrics (OTEs), a series of solution-processed thiophene-based small molecules are reported and these results indicate that OFETs semiconducting materials can be modulated through successive changes in conjugation length/side chain substituent length and molecular interaction, based on a combination of molecular design and solution-processing technique. OTEs materials can directly transform the waste heat into the electrical power without causing any pollution but their development is limited due to the poor performance especially low conductivity. Doping organic semiconductors and conjugated polymer composites are used for achieving the enhanced performance, and flexible thermoelectric generator based on these materials can be fabricated.
