报告摘要:

Advanced polymeric materials including triarylamine-containing conjugated polymers, polyimides, polyamides, polynorbornenes and nanographene-containing polymers were prepared for high performance, photonics and optoelectronics applications. Various organo-soluble polyimides and polyamides were developed via polycondensation, which can be used as high performing thermoplastic materials with excellent reprocessability and recyclability. Colorless polyimides were prepared through triarylamine-based diamine and alicyclic dianhydride for electrochromism, which exhibited fast response speed and high contrast ratio. Monolayer graphene was prepared by chemical vapour deposition (CVD) and used as transparent electrodes. In addition, triarylamine-based conjugated polymers and polynorbornenes were deposited on flexible monolayer graphene-based electrode for electrochromism. Nanographene-containing conjugated polymers and polynorbornenes (PNBs) were prepared via Suzuki Coupling reaction and ring-opening metathesis polymerization (ROMP), respectively. Both polymers showed high thermal stability up to 300oC. The nanographene-containing conjugated polymer and PNB could be highly dispersed in cyclohexylpyrrolidone (CHP) through ultrasonication, and exhibited intensive emission (485 and 465 nm) in photoluminescence-excitation (PLE) maps. The intensive and narrow emission of nanographene-containing PNB is owing to the unsymmetrical structure of nanographene and electron donating group covalently bonded to nanographene. Moreover, triarylamine-based conjugated polymers were used for high selectivity of semiconducting single-walled carbon nanotubes (SWCNT). The selectivity of nanotubes through polymer wrapping can be controlled by changing the main chain such as polytriarylamine or poly(triarylamine-fluorene), as well as adjusting the aliphatic side-chain length of polymers. Amphiphilic polytriarylamine was prepared through Suzuki coupling reaction, and used as cathode and anode buffer layers for electronics including OLED and solar cells.
