2，3-双（4-（苯基（4-（1，2，2-三苯基乙烯基）苯基）氨基）苯基）乙腈（TTF）具有独特的聚集诱导发光（AIE）特性。在1560 nm飞秒激光的激发下，可以从纳米聚集体和固态中同时观察到三光子激发发光（3 PL）和三次谐波产生信号。TTF进一步用DSPE-mPEG（一种两亲聚合物）包封以形成AIE活性纳米颗粒。基于纳米颗粒实现小鼠的3 PL脑成像。
2,3-bis(4-(phenyl(4-(1,2,2-triphenylvinyl)phenyl)amino)phenyl)fumaronitrile (TTF) shows unique aggregation-induced emission (AIE) characteristics. Under the excitation of a 1560 nm femtosecond laser, simultaneous three-photon-excited luminescence (3PL) and third-harmonic-generation signals can be observed from its nanoaggregate and the solid state. TTF is further encapsulated with DSPE-mPEG (a type of amphiphilic polymer) to form AIE-active nanoparticles. 3PL brain imaging of mice is achieved based on the nanoparticles.
