gradual increase in concentration of copolymer (DMBN-VCZ). The fluorescence of copolymer (DMBN-VCZ) can be quenched both by electron donors and acceptors where the quenching effects follow the Stern-Volmer equation. The dimolecular exciplex between copolymer (DMBN-VCZ) and N,N-dimethylaniline (DMA) are formed and the triple exciplexes are also observed in the same system.
对2,2'-二甲基丙烯酰胺基-1,1'-联萘(DMBN)与乙烯基咔唑(VCZ)共聚形成的共聚物的光物理过程进行了仔细研究。结果表明,当共聚物(DMBN-VCZ)在THF中的溶液浓度较低(<10(-3)mg / ml)时,荧光发射与DMBN单体的荧光发射吻合良好,并形成了准分子随着共聚物(DMBN-VCZ)浓度的逐渐增加。共聚物(DMBN-VCZ)的荧光可以通过电子给体和受体来猝灭,其中猝灭效果遵循Stern-Volmer方程。在共聚物(DMBN-VCZ)和N,N-二甲基苯胺(DMA)之间形成了二分子激基复合物,并且在同一系统中也观察到了三重激基复合物。
