摘要:

合成了一种18-冠-6修饰的苝酰亚胺衍生物(1), 研究了其作为主体对金属离子与阴离子的选择性识别行为. 结果表明, 主体1对Ba2+离子具有一定的选择性响应, 并可以通过Ba2+调控主体1的堆积行为; 主体1还对F-离子有选择性响应, F-与苝酰亚胺单元之间发生了阴离子-π相互作用.

Abstract:

As n-type semiconductor, perylene bisimide and its derivatives have been widely used as liquid crystals, organogels, photoinduced electron transfer systems and organic electronic devices. The construction of supramolecualr assemblies based on the π-π stacking behavior of perylene bisimide has also attracted great interest. As a good acceptor for metal ions, 18-crown-6 has been used in various sensors. To combine the stacking and optoelectronic properties of perylene bisimide with the binding ability of crown ether and obtain a unique sensing behavior, a benzo-18-crown-6 modified perylene bisimide(1) was synthesized. The selectively binding behavior of host 1 toward metal cations and anions were investigated, respectively, using UV-Vis, fluorescence and EPR. Host 1 was found to show a selectively response toward Ba2+, which can affect the stacking behavior. Furthermore, host 1 exhibited a selectively response toward F-, which should be attributed to the anion-π interaction between F- and the perylene bisimide unit.

Key words: Crown ether, Perylene bisimide, Anion-π interaction, Ion recognition
