CHARACTERIZATION OF THE CHARGE TRANSFER BETWEEN FULLERENES (C60 / C70) AND N,N,N′,N′-TETRA-(P-METHYLPHENYL)-4, 4′-DIAMINO-1,1′-DIPHENYL TELLURIDE
【摘要】 用激光光解方法研究了富勒烯(C60/C70)与N,N,N′,N′-四-(对甲基苯)-4,4′-二胺-1,1′-二苯碲醚电荷转移复合物的特征.通过观察在近红外区瞬间吸收带,富勒烯(C60/C70)激发三线态,富勒烯(C60/C70)阴离子自由基和N,N,N′,N′-四-(对甲基苯)-4,4′-二胺-1,1′-二苯碲醚阳离子自由基的出现,测定了在苯腈溶液中从N,N,N′,N′-四-(对甲基苯)-4,4′-二胺-1,1′-二苯碲醚到富勒烯(C60/C70)激发三线态的量子转化产率和电子转移常数.
【Abstract】 Characterization of the charge transfer between fullerenes (C60 / C70) and N,N,N′,N′-tetra-(p-methylphenyl)-4,4′-diamino-1,1′-diphenyl telluride (TPDATe) has been studied by nanosecond laser flash photolysis. Quantum yields (Φet) and rate constants of electron transfer (ket) from TPDATe to excited triplet state of fullerenes (()3C60* / ()3C70*) in benzonitrile have been evaluated by observing the transient absorption bands in the near-infrared region where the ()3C60* / ()3C70*, radical anions of fullerenes (C·-60/ C·-70) and radical cation of TPDATe (TPDATe·+) appear.
【Key words】 fullerenes (C60 / C70); N,N,N′,N′-tetra-(p-methylphenyl)-4,4′-diamino- 1,1′-diphenyl telluride (TPDATe); electron transfer; laser photolysis;
