SYNTHESIS AND FLUORESCENCE PROPERTIES OF FULLERENE-INDOLE DYAD

利用肌氨酸与不同的氮 -烷基取代的 3 吲哚醛反应生成的氮Ylide,通过 1,3 偶极环加成反应 ,合成了五个C6 0 吲哚二元化合物 ,用1 HNMR、FT IR、UV Vis等作了结构表征并研究了它们的荧光特性。五个化合物的荧光性质相似 ,在大约 70 8nm处C6 0 荧光发射最强 ,与母体C6 0 相比 ,量子产率增加了约 4倍 ,荧光寿命约为 1.2ns ,与母体C6 0

Five C-60-indole adducts have been synthesized by 1, 3-dipolar cycloaddition reaction. These compounds are characterized by H-1 NMR, FT-IR, UV-Vis. The fluorescence spectra show that they are Similar to each other, with maximurn 0-->0 emission at about 708 nm in CHCl3 and fluorescence yields ca. 4 times, higher than that of pristine C-60. The fluorescence lifetime (tau(F)) of 1a-e is ca. 1.2 ns in toluene, which is very similar to that of C-60.
