合成了聚[2,6-萘二甲酸(聚四亚甲基醚二醇)酯](1)和聚[对苯二甲酸(聚四亚甲基醚二醇)酯](2);研究了它们在溶液和本体中的荧光光谱;论证了链间和链内非相邻生色团间有激基缔合作用存在。观察了聚合物1由稀到浓的氯仿溶液的激基缔合物荧光强度与单生色团荧光强度比值的变化,得到溶液中高分子线团的动态接触浓度C_s=0.26g/dL;亚浓区到浓区的转变浓度C~+=7g/dL。在聚合物1的本体中得到基态芳环层叠缔合物直接激发到激基缔合物的实验证据。
Poly (2,6-naphthalate (polytetramethylene ether glycol) ester] (1) and poly [terephthalate (polytetramethylene ether glycol) ester] Their fluorescence spectra in solution and bulk were demonstrated. The existence of excitatory association between non-adjacent chromophores in chains and in chains was demonstrated. The change of the fluorescence intensity of the excimer and the fluorescence intensity ratio of the single chromophore from dilute to concentrated chloroform solution was observed. The dynamic contact concentration (C_s = 0.26 g / dL) District to the concentration of the concentration of C ~ + = 7g / dL. In the bulk of polymer 1, we obtained the experimental evidences that the ground state aromatic ring cascades were directly excited to excimer.
