Because zinc ion plays various kinds of important roles in human physiopathology, development of sensitive and noninvasive ion sensing technique is important to trace and visualize free zinc ions. However, most of the attention has been focused to the detection of endogenous free zinc ions using typical structure of a fluorescent zinc sensors which is composed of a conventional fluorophore and a well-known zinc-specific receptor such as di(2-picolyl)amine (DPA), N,N-di(2-picolyl)- ethylenediamine (DPEN), tris(2-picolyl)amine (TPA), or N,N,N′-tris(2-picolyl)ethylenediamine (TRPEN). In this work, we have designed and synthesized novel kinds of sensing materials which are based on excited state intramolecular proton transfer (ESIPT) fluorophore, that results in the formation of two tautomeric forms in the excited state of the probe, normal and tautomer forms are very successful for the design of probes with dual fluorescence. For orange-red emitting sensing part, naphthol and thiazole-based ESIPT fluorophore, 3-(4,5-diphenylthiazol-2-yl)naphthalen-2-ol, was synthesized and zinc-selective di(2-picolyl)amino (DPA) unit was introduced as a receptor part.
