激基缔合物是由一个激发态分子和一个基态分子形成的复合物,组成激基缔合物的两个分子平面必须彼此平行呈夹心面包式构型。在某些情况下,两个芳香环在基态时就呈激基缔合物的构型并有很强的相互作用,形成基态复合物一二聚体。人们对平面结构的芳香化合物分子形成的激基缔合物已经进行了大量研究,并且注意到非平面的芳香化合物分子很难形成激基缔合物。两个芳香环通过一个碳-碳单键连接组成的分子,多 An excimer is a complex formed by an excited state molecule and a ground state molecule. The two molecular planes that make up an excimer must be parallel to each other to have a sandwich-type configuration. In some cases, the two aromatic rings exhibit an exciton-associated configuration and have a strong interaction at the ground state, forming a ground-state complex-dimer. A great deal of research has been conducted on exciplexes formed by aromatic compound molecules having a planar structure, and it is noticed that non-planar aromatic compound molecules hardly form exciplexes. Two aromatic rings through a carbon-carbon single bond composed of molecules, and more
