Abstract
Abstract Novel turn-on fluoroionophores 2 and 3 based on highly fluorescent 8-methoxyquinoline were developed in which a sequential singlet–singlet energy transfer, ISC, and triplet–triplet energy transfer occurred leading to a fluorescence ‘off’ state. They showed substantially enhanced fluorescence in the presence of transition metal ions such as Zn 2+ , Cu 2+ , Pb 2+ , and Hg 2+ and an extremely high selectivity toward Zn 2+ by 3 .
