Dendron conjugated branches of stilbene and 4-styrylstilbene groups have been attached to resor-cinarene cores. A noticeable effect in solution for all dendrimers was observed in the fluorescence quantum yield. The optical properties do not change with concentration in solution. The optical properties of thin films are identical to those of the solutions indicating the absence of intermolecular interactions. The dendrimers were characterized by 1H, 13C NMR, FTIR, UV-Vis, fluorescence spectroscopy, MALDI-TOF or FAB+ mass spectrometry, and elemental analysis.
二苯乙烯和4-苯乙烯基二苯乙烯基团的树枝状共轭支链已连接到间苯二酚杯芳烃核上。在所有树枝状聚合物的溶液中，荧光量子产率都观察到了显著的效果。光学性质不会随溶液浓度而改变。薄膜的光学性质与溶液的光学性质相同，这表明不存在分子间相互作用。通过1H、13C核磁共振、傅里叶变换红外光谱、紫外可见光谱、荧光光谱、基质辅助激光解吸电离飞行时间质谱或快原子轰击正离子质谱以及元素分析对树枝状聚合物进行了表征。
