在联苯基基序上设计合成了一种新的荧光受体1，其中吡啶酰胺部分作为结合位点，在联苯基间隔剂的控制下表现出选择性的异苯二甲酸酯和H2PO4络合体。利用结合诱导的发射量增加来测定I对一系列阴离子（如不同的二羧酸盐、HSO4-、CIO4和H2PO4）的选择性和灵敏度。通过H-1 NMR， UV-vis和荧光光谱方法确定了其结合特性(C) 2009 Elsevier Ltd All rights reserved
A new fluorescent receptor 1 built on biphenyl motif has been designed and synthesized Pyridinium amide moiety in 1 acts as binding site and shows selective complexanon of isophthalate and H2PO4 under the mastery of biphenyl spacer. Binding-induced increase in emission was used to determine the selectivity and sensitivity of I toward a series of anions such as different dicarboxylates, HSO4-, CIO4, and H2PO4. The binding characteristics were established by H-1 NMR, UV-vis, and fluorescence spectroscopic methods (C) 2009 Elsevier Ltd All rights reserved
