Abstract

Fluorescent photoinduced electron transfer (PET) fluoroionophore (2c) that consists of diaza-12-crown-4 and two 1-pyrenylmethyl pendants shows fluorescent enhancement with various metal cations. The sensor (2c) exhibited Zn2+ selectivity and in the presence of this cation the host fluorescence was increased by a factor of 38.
