Abstract

New calix[4]pyrroles bearing dipyrrolylquinoxaline as strapping elements have been synthesized and characterized by spectroscopic means. The binding behavior of these receptors at 25 degrees C was investigated first by proton NMR spectroscopy in CD(3)CN/DMSO-d(6) (9:1 v/v), as well as by UV-vis spectroscopy and isothermal titration calorimetry (ITC) in CH(3)CN/DMSO (97:3 v/v). The receptors displayed a selective colorimetric response when exposed to the fluoride, dihydrogen phosphate, and acetate anions (studied in the form of the corresponding tetrabutylammonium salts) and an enhanced affinity as compared to a comparable calix[4]pyrrole system lacking the dipyrrolylquinoxaline-containing strap.

摘要

已合成了带有二吡咯基喹喔啉作为束缚单元的新型杯[4]吡咯,并通过光谱手段对其进行了表征。首先在CD(3)CN/DMSO-d(6)(9:1 v/v)中通过质子核磁共振光谱,以及在CH(3)CN/DMSO(97:3 v/v)中通过紫外可见光谱和等温滴定量热法(ITC)研究了这些受体在25℃时的结合行为。当暴露于氟离子、磷酸二氢根离子和醋酸根离子(以相应的四丁基铵盐形式研究)时,这些受体表现出选择性比色响应,并且与缺乏含二吡咯基喹喔啉链的类似杯[4]吡咯体系相比,亲和力增强。
