摘要

基于4,4'-二氨基二苯甲烷(DPM)的荧光探针已被报道。我们设计了一种新的荧光探针1，以双(4-甲氧基苯基)马来酰亚胺和氨基分别作为荧光团和传感部分，其中DPM作为传感分子的平台，利用其优势。在MeCN、CH2Cl2和甲苯中加入三氟乙酸后，1的荧光强度增加，表明1表现为质子传感器。在MeCN和不同pH缓冲液的混合物中观察到1的荧光光谱变化。此外，1与2-甲酰基吡啶形成席夫碱骨架，作为金属(锌或镍)离子传感器。1的金属离子感应特性可应用于与电路。

Evaluation of 4,4'-Diaminodiphenylmethane as a Platform for Proton,

4,4'-Diaminodiphenylmethane (DPM)-based fluorescent probes have been reported. We designed a new fluorescent probe 1, having bis(4-methoxyphenyl)maleimide and an amino group as a fluorophore and a sensing part, respectively, in which DPM was used as a platform for sensing molecules to utilize its advantage. The fluorescence intensity of 1 increased upon adding trifluoroacetic acid in MeCN, CH2Cl2, and toluene, indicating that 1 showed as a proton sensor. The fluorescence spectral change of 1 was observed in a mixture of MeCN and various pH buffers. Moreover, 1 behaved as a metal (zinc or nickel) ion sensor with 2-formylpyridine by forming the Schiff base skeleton. The metal ion sensing behavior of 1 could be applied to an AND circuit.

期刊介绍： Since its inception in 1973 HETEROCYCLES has provided a platform for the rapid exchange of research in the areas of organic, pharmaceutical, analytical, and medicinal chemistry of heterocyclic compounds in addition to communications, papers, reviews, a special section of the journal presents newly-discovered natural products whose structure has recently been established. Another section is devoted to the total synthesis of previously documented natural products with heterocyclic ring systems. Due to the fact that the journal is able to publish articles within two months of receipt of the manuscripts, researchers in this field can obtain up-to-date information on heterocyclic research by reading Heterocycles regularly. Audience: Organic and Physical Organic Chemists, Biochemists, Pharmacologists and Scientists studying heterocyclic compounds
