Effect of Structural Variation on Spectral, NLO Properties, and Biological Activity of Pyrrole Hydrazones.

This paper describes spectral, non-linear optical (NLO), and biological activity variation of pyrrole hydrazones as a result of structural variation. In order to study structure-property variation, pyrrole hydrazones (, , and ) were synthesized in both solid and solution phases. The grinding solvent-free method becomes rapid, easy, convenient, useful, sustainable, and eco-friendly green synthesis as compared to the classical solution phase reactions.
