Elucidation of a detection mechanism of a fluorescent sensor based on photo-induced electron transfer for water

Abstract

In order to elucidate a detection mechanism of photo-induced electron transfer (PET)-type fluorescent sensor for water, we have synthesized anthracene-(aminomethyl)-4-cyanophenylboronic acid (AminoMeCNPhenylB(OH)2) TF-2 by the deprotection of pinacol ester (Pin)...

Anthracene-(aminomethyl)phenylboronic acid ester-immobilized glass substrates as fluorescent sensing materials based on photo-induced electron transfer for detection and visualization of water

“…In recent years, there has been increasing interest in the development of fluorescent sensors and their functional materials, including polymers, membranes, and sensorimmobilized substrates for detecting and visualizing water in solids, solutions, and gas or on material surfaces, because such fluorescent sensing systems for water are crucial to environmental and quality control monitoring, industrial processes, food inspection and so on. Actually, some kinds of organic fluorescent sensors for water, based on ICT (intramolecular charge transfer), [25][26][27][28][29][30][31][32][33] ESIPT (excited state intramolecular proton transfer), [34][35][36][37] PET (photo-induced electron transfer), [38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] or solvatochromism have been developed which exhibit photophysical changes in wavelength, intensity, and lifetime of fluorescence emission depending on the water content. Hence, over the last decade and a half, we continued to make much effort to design and develop PET-type fluorescent sensors for water in solvents.…”
