The synthesis of conjugates of perylene diimide (PDI) and naphthalene diimide (NDI) modified with two benzo-21-crown-7 ethers (B21C7) are herein described. Their self-assembly behavior in various solvents was investigated particularly in aqueous medium, due to the recently discovered hydrophilic properties of B21C7 crown macrocycle. An unexpected fluorescence quenching phenomenon was observed in the PDI-B21C7 macrocycle conjugate in chloroform. The detailed UV–vis absorption and fluorescence spectra of these PDI/NDI derivatives in different solvents as well as their morphologies were investigated.

苝和萘冠大环共轭物在水介质中的自组装行为



本文描述了用两种苯并-21-冠-7醚(B21C7)修饰的苝二酰亚胺(PDI)和萘二酰亚胺(NDI)缀合物的合成。由于最近发现的 B21C7 冠大环的亲水特性,研究了它们在各种溶剂中的自组装行为,特别是在水介质中。在氯仿中的 PDI-B21C7 大环缀合物中观察到意想不到的荧光猝灭现象。研究了这些 PDI/NDI 衍生物在不同溶剂中的详细紫外可见吸收光谱和荧光光谱及其形貌。
