水杨醛衍生物激发态下的质子转移过程及在荧光探针领域的应用
Excited State Intramolecular Proton Transfer of Salicylaldehyde Derivatives and Its Application in Fluorescent Probe Field
摘要
Abstract
According to the electronic structure control theory,the electron withdrawing substituent was introduced to the para-positon of phenol hydroxyl group to stable the ketone conformation,and the target compound,2-hydroxy-5-(4-cyanophenyl)-benzaldehyde (CN-SA),was prepared.Series of spectral tests show that,CN-SA not only shows the typical excited state intramolecular proton transfer (ESIPT) fluorescence characteristics,but also significantly increases the ketone distribution proportion in radiation transition process,so that the fluorescence intensity and color change visibly.CN-SA not only exhibites selective recognition for the external solvent environment,but also has specific response and quantitative analysis ability for aggregation process (aggregation effect) and the hydrogen bond formation ability following environmental changes (pH effect and anions effect).With little structure tuning,CN-SA could realize alcohol and ketone conformation distribution changes and can be used as a simple multiple stimulation-responsive fluorescence probe.关键词
