Abstract

[reaction: see text] 6(A),6(D)-Bispyridinio-appended gamma-cyclodextrin effectively enhanced the excimer fluorescence of 2-naphthylacetate. This increase derived from the increase of formation of the 1:2 complex between the cation-charged gamma-cyclodextrin and 2-naphthylacetate by the electrostatic interaction between the host and the guest.

摘要

[反应：见正文] 6(A),6(D)-双吡啶基修饰的γ-环糊精有效地增强了2-萘乙酸酯的准分子荧光。这种增强源于阳离子化的γ-环糊精与2-萘乙酸酯之间通过主客体间静电相互作用形成1:2复合物的增加。
