Tautomerism in the Solid State

Solid state tautomerism in 2-((phenylimino)methyl)naphthalene-1-ol

“…Proton tautomerism plays an important role in many fields of chemistry and biochemistry [1][2][3][4][5]. Molecules giving rise to excited state tautomers by intramolecular proton transfer enjoy applications as laser dyes, in higher energy radiation detectors and molecular memory storage devices, as fluorescent probes and also as polymer protecting agents [6].…”

Crystal structure of N-(3-hydroxyphenyl)-5-chlorosalicylideneimine, C13H10ClNO2

“…Schiff bases of salicylaldehyde with amines (anils) comprise ac hemical system undergoing hydrogen-atom tautomerism between enol and keto forms and show the phenomena of solid state photochromism and thermochromism [1][2][3].…”

Photoinduced excited state intramolecular proton transfer and spectral behaviors of Aloesaponarin 1

“…Aloe is an active and frequently used ingredient in hundreds of skin lotions, sun blocks for UV protection, and different cosmetics for its cosmetic and healing properties [1][2][3][4][5][6][7][8][9][10][11]. Numerous Aloe species around the world are used in conditions ranging from dermatitis to cancer [1][2][3].…”
