过去文献上报道的激基复合物,多数是由电离能比较小的电子给体和电子亲和力比较大的电子受体所组成。但是我们实验室研究了一系列电离能和电子亲合力都比较接近的“给体”和“受体”,它们也能形成激基复合物。因此我们曾经指出激基复合物应分为两类,在电离能和电子亲合力都比较接近的体系中,与生色团相连的侧基的亲电子能力的大小,对激基复 In the past, exciplexes reported in the literature mostly consisted of electron donors with relatively small ionization energies and electron acceptors with large electron affinity. However, our laboratory has studied a series of “donor” and “acceptor” that both have relatively close ionization energies and electron affinity, and they also form exciplexes. Therefore, we have pointed out that exciplexes should be divided into two categories, in the ionization energy and electron affinity are relatively close to the system, the chromophore attached to the electrophilic side of the size of the electrophilic group
