Azobenzamide-based proteomorphous objects as a light/pH-induced photoswitchable module

Abstract

Azobenzamide-based molecular scaffolds viz. (E)-4,4′(diazene-1,2- diyl)bis(N-pyridin-3-yl)benzamide (1) and (E)-4,4′(diazene-1,2-diyl)bis(N- pyridin-4-yl)benzamide (2), yield proteomorphous architectures i.e., secondary "β-pleated sheet" and tertiary "β-hairpin" respectively, that offer "optical data storage" competence as a result of reversible light-induced conformational changes in organic solvent. © The Royal Society of Chemistry 2014.
