摘要
本文旨在研究聚β-乙烯基萘链内激发态缔合物与基态受体分子1,4-二氰基苯相互作用后,形成三分子激基复合物的机理,用稳态和时间分辨荧光光谱技术证明了分子间的三分子激基复合物形成机理:测定了分子内激基缔合物的形成速度; 三分子激基复合物的形成速度常数,详细讨论了由激发态激基缔合物形成分子间三分子激基复合物的处理模型。
In this paper, a mechanism of a triple exciplex formed between an excimer formed by non-adjacent chromophores of poly (β-vinyl) naphthalene (PβVN) and an acceptor of 1, 4-dicyanobenzene (DCB) have been proved by steady-state and time-resolved flourescence spectroscopic technique. A rate constant of the excimer formation, k_3=3.5×10~9s^(-1); a ratc constant of the triple exciplex formation, k_3=4.0×10~9(mol/L)^(-1)s^(-1), have been determined. A theoretical model for the triple exciplex formation is discussed.
