合成了一种C60-噻吩吡咯烷衍生物1。以1H NMR,13C NMR,FTIR,和FAB-MS进行了结构表征。测量其在甲苯溶液中的荧光发射光谱,并在此最大发射波长下测得其荧光寿命为7.47 ns,而C60在室温的荧光寿命大约是1.2 ns。说明富勒烯吡咯烷衍生物1在激光激发下发生了加成基团噻吩与母体C60之间的分子内能量转移和电荷传递,有可能产生长寿命的电荷分离态。
A C60-thiophene pyrrolidine derivative 1 was synthesized. The structures were characterized by 1H NMR, 13C NMR, FTIR and FAB-MS. The fluorescence emission spectra were measured in toluene solution, and the fluorescence lifetime was 7.47 ns at the maximum emission wavelength. The fluorescence lifetime of C60 at room temperature was about 1.2 ns. It is concluded that fullerene pyrrolidine derivative 1 undergoes intramolecular energy transfer and charge transfer between the addition group thiophene and the parent C60 under laser excitation, and it is possible to generate a long-lived charge-separation state.
