Abstract
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
