Influence of Hydrogen Bonding on the Photophysical Properties of Diethylamino Hydroxybenzoyl Hexyl Benzoate

In this study, we investigated the effects of different hydrogen bond types on photophysical properties diethylamino hydroxybenzoyl hexyl benzoate (DHHB) by systematically exploring changes in spectral DHHB protic and aprotic solvents. The formation stability bonds were also studied, demonstrating that system mainly existed form intramolecular at low concentrations (≤5 μg/mL). these circumstances, fluorescent intensity, molar absorption coefficient changed little, indicating had little effect DHHB. With an increase concentration, number intermolecular increased significantly increased, conducive to improving UV temperature, decreased, which reduced performance solvent, contained DHHB–solvent bonds. proportion solvent system, intensity integral area between molecules was beneficial terms
