【摘要】 合成了一种新的C60-卤代苯吡咯烷衍生物1,以1HNMR、13CNMR、FT-IR、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5.26ns,而C60在室温的荧光寿命大约是1.2ns。说明C60-卤代苯吡咯烷(1)在激光激发下发生了加成基团苯环与母体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。理论计算化合物1的电子结构和前线轨道进一步验证了上述结果。更多还原

【Abstract】 A new fulleropyrrolidine 1 containing 2-fluoro-4-Bromid-benzenee dyad was synthesized. The molecular structure was identified and characterized by 1H NMR,13C NMR,FTIR,UV and FAB-MS. The fluoresence emission spectra and fluoresence lifetime under the largest emission wavelength were measured in toluene. It was found that the fluorescence lifetime of 1 was 5.26 ns,which was larger than the lifetime of C60(1.2 ns). This result showed that intramocular charge and energy-transfer had occurred between benzenee and C60 in the 1,and the long lived charge-separated state may occur in the 1. Electronic structure and frontier orbitals of 1 was calculated. Theoretical calculations and xperiments provided a coherent picture.更多还原
