我们曾根据激基复合物的溶剂效应论证了激基复合物应分为两类,以及证明在电子给体和电子受体的电离能和电子亲合力都几乎相等时,与电子给体相连的侧基和与电子受体相连的侧基之间的相互作用,对形成激基复合物起重要作用。本文报道即使在电离能和电子亲合力相差都比较大的体系中,侧基对形成激基复合物也有很大影响。 We have demonstrated that the exciplexes should be classified into two groups based on the solvent effect of the exciplex and to demonstrate that the electron donor and electron acceptor are both connected to the electron donor when their ionization energies and electron affinity are nearly equal The interaction between pendant groups and pendant groups attached to electron acceptors plays an important role in the formation of exciplexes. This paper reports that pendant groups have a significant impact on the formation of exciplexes, even in systems with large differences in ionization energies and electron affinities.
