Fluorescent chemosensors-molecules whose fluorescence emission changes in response to a reversible binding event-require both a substrate binding domain and a reporting fluorophore. Our approach to chemosensor development is based on a combination of a new signaling mechanism and a modular fluorophore synthesis. The latter feature has facilitated detailed study of the properties of polyarylpyridine fluorophores, and has led to the identification of a visibly-emissive pyridine as a promising lead structure for chemosensor development. The results of this study are described herein. (C) 2004 Elsevier Ltd. All rights reserved.
