以联噻吩和联苯为结构单元，通过Suzuki交叉偶联合成了一种在460 °C下稳定的微孔联噻吩聚合物（MBP）。所得MBP产物显示峰值在530 nm处的绿色荧光，并且最有趣的是，在用800 nm飞秒激光激发时从MBP可观察到双光子荧光。
A microporous bithiophene polymer (MBP) stable up to 460 °C was synthesized using bithiophene and biphenyl as building blocks through Suzuki cross-coupling. The as-obtained MBP product exhibits green fluorescence peaked at 530 nm, and most interestingly, a two-photon fluorescence was observable from MBP upon excitation by an 800 nm femtosecond laser.
