Abstract

A blue-red reversible optical switch was created by combining Eu^III, pyridine, and a fluorescent organic chromophore. In the initial stage Ch-Eu^III interaction was responsible for the Eu^III emission quenching. The irradiation of pyridine brought about its protonation and formation of the hydrogen-bonded aggregates. The high electron-accepting ability of pyridinium cations lead to donor-acceptor interaction with the chromophore, and quenching of fluorescence in the presence of the EuCl₃ or (Et)₄NCl.
