Readily available 5-aryl-2,2'-bipyridines and their derivatives are a unique family of fine-tunable chromophores, where changes in the substitution patterns, solvation and coordination are translated into dramatic spectral changes. They exhibit sensitive and selective response to zinc ions with dramatic increases in emission intensity or significant red-shifts of emission maxima. (c) 2006 Elsevier Ltd. All rights reserved.

A wide series Of Substituted bipyridines were obtained through the synthesis of 1,2,4-triazines and their aza Diels-Alder reactions. The reported method facilitates the synthesis of functionally diverse bipyridines that provides fine-tuning of photophysical properties of new ligands and their Zn(II) and Ru(II) complexes. Some of substituted bipyridines exhibit 'off-on' fluorescence response toward Zn 2 cations. (C) 2008 Elsevier Ltd. All rights reserved.
