设计并合成了新型杯[4]芳烃阴离子受体1-3。通过UV-vis、ESI-MS和H-1 NMR谱研究了它们对各种阴离子的传感性能。实验结果表明，受体1与H2 PO 4-、F-和AcO-之间存在两种相互作用模式，其中受体1以氢键作用模式选择性地结合H2 PO 4-、F-和AcO-，而受体2和3则以酸碱作用模式与碱性阴离子（F-、AcO-和H2 PO 4-）发生去质子化反应。受体2和3被证明是有效的“裸眼”传感器的F-和AcO-与显着的颜色变化。(C)2012爱思唯尔有限公司保留所有权利。
Novel calix[4]arene-based anion receptors 1-3 with bis-squaramide moieties were designed and synthesized. Their sensing properties with various anions were investigated by UV-vis, ESI-MS, and H-1 NMR spectra. The experimental results revealed that there were two types of interaction modes where receptor 1 bound biologically important H2PO4-, F-, and AcO- ions selectively over other anions in the hydrogen bonding interaction mode, while receptors 2 and 3 displayed deprotonation behavior with basic anions (F-, AcO-, and H2PO4-) via acid-base interaction mode. Receptors 2 and 3 were proved to be efficient 'naked-eye' sensors for F- and AcO- with marked color changes. (C) 2012 Elsevier Ltd. All rights reserved.
