Studies of the interactions of 4-carboxyl-2,6-dinitrophenylazohydroxynaphthalenes with CT-DNA in aqueous medium

Emerging ground and excited state dipole moments and external electric field effect on electronic structure. A solvatochromism and theoretical study on 2-((phenylimino)methyl)phenol derivatives

“…Variable temperature X-ray crystallographic analyses of 2-hydroxy Schiff base indicate that enol form is usually more stable than the keto form [14]. The keto form is predominantly zwitterionic in crystals and stabilized in crystals by hydrogen bonding and electrostatic intermolecular interactions [15][16][17][18][19][20]. Most of these studies were focused on the determination of tautomeric preferences, and investigation of the role of substituents on the position of the tautomeric equilibria, solvato-, iono-, thermo-and photochromic effects [21][22][23][24][25][26][27][28][29][30][31].…”
