Development of highly-sensitive fluorescence PET (photo-induced electron transfer) sensor for water: anthracene–boronic acid ester†
Abstract
Anthracene–boronic acid ester OF-2 having a cyano group as an electron-withdrawing substituent was designed and developed as a highly-sensitive fluorescence PET sensor for detection of a trace amount of water in various solvents (polar, less polar, protic and aprotic solvents).
