本工作对磺化聚苯乙烯-吖啶橙体系的光物理行为进行了研究。发现吖啶橙的荧光强度强烈地依赖于所用染料和聚电解质的当量比(P/D)。在P/D=100时观察到有最大的荧光强度。经过校正,此值和Fox等研究苯乙烯和乙烯基共聚物的能量转移中所得结果基本一致。这表明在高分子电解质-染料络合物中能发生有效的能量转移。 本工作还研究了亚甲蓝对吖啶橙荧光的猝灭效应。观察到当体系中加入聚电解质时猝灭效应得以增强。
In this work, the photophysical behavior of sulfonated polystyrene-acridine orange system was studied. Fluorescence intensity of acridine orange was found to strongly depend on the equivalence ratio (P / D) of dye and polyelectrolyte used. The maximum fluorescence intensity was observed at P / D = 100. After correction, this value and Fox and other studies of styrene and vinyl copolymer energy transfer results obtained are basically the same. This shows that efficient energy transfer can occur in the polymer electrolyte-dye complex. The work also studied the methylene blue fluorescence of acridine orange fluorescence quenching effect. It was observed that the quenching effect was enhanced when the polyelectrolyte was added to the system.
