合成了N-甲基-2-(4’-双噻吩基)-[60]富勒烯吡咯烷,以1H NMR,13C NMR,FTIR,FAB-MS和UV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6.03 ns,而C60在室温的荧光寿命大约是1.2 ns。表明N-甲基-2-(4’-双噻吩基)-[60]富勒烯吡咯烷在激光激发下,加成基团双噻吩环与母体C60之间发生了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,为下一步制备聚噻吩富勒烯及太阳能电池的组装提供了光电等基本参数。
Synthesis of N - methyl - 2 - (4’- bithienyl) - [60] fullerene pyrrolidine, 1H NMR, 13C NMR, FTIR, FAB-MS and UV structural characterization. The fluorescence emission spectra were measured in toluene solution and the fluorescence lifetime was found to be 6.03 ns at this maximum emission wavelength, while the fluorescence lifetime of C60 at room temperature was about 1.2 ns. It is shown that the intramolecular energy transfer and the charge between the addition group dithiophene ring and the parent C60 under the condition of laser excitation are the result of N-methyl-2- (4’-bithienyl) - [60] fullerene pyrrolidine Transfer, it is possible to produce a long-lived charge-separation state, and provide basic parameters such as optoelectronics for the next step of preparing the polythiophene fullerene and the assembly of the solar cell.
