Novel perylene-3,4,9,10-tetracarboxdiimides (PDI) dyes functionalized with polyphenylene dendrimers attached at the bay region are reported. Derivatives of PDI bearing polyphenylene dendrimers up to the second generation, substituted with an increasing number of triphenylamine (TPA) moieties at the periphery, as well as a related nondendronized model compound were prepared. Intramolecular energy transfer was demonstrated by the observation of PDI emission on excitation of the triphenylamines, and electron transfer was detected by comparing photoluminescence quenching in solvents of different polarity.
报道了在湾区连接有聚苯撑树枝状大分子的新型苝-3,4,9,10-四羧酸二亚胺(PDI)染料。制备了带有聚苯撑树枝状大分子直至第二代的PDI衍生物,其在外围被越来越多的三苯胺(TPA)基团取代,以及一种相关的非树枝状模型化合物。通过观察三苯胺激发时的PDI发射证明了分子内能量转移,并通过比较不同极性溶剂中的光致发光猝灭检测到了电子转移。
