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 Zn2+ cations.
