Abstract
A convenient route was successfully developed for the synthesis of novel heterocycles such as pyridine-3-carbonitriles 4 from chalcone 3 in good yields. The pyridine-3-carbonitrile derivatives synthesized were further studied for their photophysical properties and observed that absorption and emission was changed, due to the chromospheres at C4-position in phenyl ring and C2-position in pyridine-3-carbonitrile derivatives.
