摘要: 本文设计合成了N6-对甲苯磺酰胺腺嘌呤(I)和邻苯二对甲苯磺酰胺(Ⅱ)两种主体化合物.通过对其与阴离子物种之间相互作用的研究发现,它们在乙腈溶液中和Cl-、Br-、NO3-、NO2-、HSO4-、Ac-、F-几种阴离子相互作用时,仅对F-具有专一的选择性识别作用.F-离子可使I和Ⅱ主体的荧光吸收猝灭并发生红移.通过试验证明,F-离子和I、Ⅱ主体的识别作用机理是因形成了激基缔合物.

Abstract: Two sulfamide host compounds (I, Ⅱ) were synthesized and their fluorescence character was studied. Through the study of their recognition with Cl-, Br-, NO3-, NO2-, HSO4-, Ac- and F- anions in CH3CN, it was found that both of the hosts have a selective recognition with F-. An exciplex formed by the addition of F-, in which the fluorescence intensity of compound I, Ⅱ at 317 nm decreases and a new broad emission band peaked at 403 nm emerges with increasing intensity.

Key words: fluorescence chemosensor, anions, fluorescence recognition
