Preparation, spectroscopic and antibacterial studies on charge-transfer complexes of 2-hydroxypyridine with picric acid and 7,7',8,8'-tetracyano-p-quinodimethane

摘要: The reactions of electron acceptors such as picric acid (HPA) and 7,7',8,8'-tetracyano-p-quinodimethane (TCNQ) with 2-hydroxypyridine (HPyO) have been investigated in EtOH at room temperature. Based on elemental analysis IR spectra the solid CT-complexes along photometric titration curves for reactions, data obtained indicate formation 1:1 charge transfer complexes [(H2PyO)(PA)] [(PyO)(HTCNQ)], respectively. infrared (1)H NMR spectroscopic a interaction associated proton migration from acceptor to donor followed by intramolecular hydrogen bonding complex. Another was observed [(PyO)(HTCNQ)] constants (KCT) are shown be strongly dependent type structure acceptors. Factors affecting CT-processes kinetics thermal decomposition studied. CT were screened their antibacterial activities against selected bacterial strains.
