title: Resorcin[4]arene cavitand with 1,3,2-benzodiazaborolyl walls as a fluorescence receptor for ammonium cations.
abstract: Resorcin[4]arene cavitand 1 with 1,3,2-benzodiazaborolyl walls was newly synthesized. It showed a large blue shift in the fluorescence spectra upon selective complexation with alkyltrimethylammonium salts in CH(2)Cl(2)-DMSO (9 : 1 v/v); this shift was detectable with the naked eye.
