The effect of acid-base interactions on the photophys. properties of 6,7-dimethoxy-3,4-dihydroisoquinoline in protic solvents is studied by the methods of steady-state and picosecond spectroscopy. The specific features of the spectral and luminescent properties of solutions of 6,7-dimethoxy-3,4-dihydroisoquinoline are connected with the presence of emission centers of 2 types-solvated initial mols. and their protonated cationic forms. Considerable long-wavelength shifts observed in the electronic absorption and fluorescence spectra of the cationic form of the mol. as compared to the spectra of its initial form are caused by the elongation of a conjugated chain present in the fragment of the mol. that separates the N atom and the O atoms of the methoxy groups. The transition of the cationic form of the mol. to an excited electronic state is not accompanied by a change in its dipole moment. In the experiment, the researchers used many compounds, for example, 6,7-Dimethoxy-3,4-dihydroisoquinoline (cas: 3382-18-1Formula: C11H13NO2).
6,7-Dimethoxy-3,4-dihydroisoquinoline (cas: 3382-18-1) belongs to isoquinoline derivatives. Quinoline and isoquinoline skeletons are among the most attractive frameworks with a wide range of biological and pharmacological activities. Most traditional methods of generating isoquinoline do so via oxidative aromatization of dihydro- or tetrahydro-isoquinolines, usually offering some environmental or economic advantage.Formula: C11H13NO2
