摘　　要：富勒烯 (C60 /C70 )与N ,N ,N′ ,N′ 四 (对甲苯基 ) 4,4′ 二胺 1,1′ 二苯硒醚 (TPDASe)间在激光光诱导条件下 ,发生了分子间的电子转移过程 .在可见 -近红外区 ( 60 0～ 12 0 0nm) ,观测到了TPDASe阳离子自由基、富勒烯 (C60 /C70 )激发三线态和阴离子自由基 ,在苯腈溶液中 ,观测瞬态谱测定了电子从TPDASe转移到富勒烯 (C60 /C70 )激发三线态的量子转化产率(ΦTet)和电子转移常数 (Ket) .The photoinduced electron-transfer between N,N,N′,N′-tetra-(p-methylphenyl)-4,4′-diamino-1,1′- diphenyl selenide (TPDASe) and fullerene (C 60/C 70) occurred in benzonitrile by nanosecond laser flash photolysis. Transient absorption spectral measurements were carried out during laser flash photolysis of a mixture of the fullerenes (C 60/C 70) and TPDASe at 532 nm. The electron transfer from the TPDASe to the excited triplet state of the fullerenes (C 60/C 70), quantum yields and rate constants of electron transfer from TPDASe to the excited triplet state of fullerenes (C 60/C 70) in benzonitrile have been evaluated by observing the transient absorption bands in the near-IR region where the excited triplet state, radical anion of fullerenes (C 60/C 70) and radical cations of TPDASe appear.
