Deprotonation-induced enhancement in fluorescence of 2-((2-hydroxybenzylidene)amino)phenol, a Schiff base
Excited state dynamics of neutral and anionic forms of 2-((2- hydroxybenzylidene)amino)phenol (HBAP), a Schiff base, has been elucidated using time resolved fluorescence spectroscopy.The neutral molecule exhibits keto-enol tautomerism.So, the fluorescent cis-keto excited state is formed by direct excitation as well as x515ea-bh55-cb ultrafast excit
