Synthesis and photophysical properties of N-styrylazinones
(Chemical Equation Presented) N-Styrylazinones and 1-styrylbenzotriazine were synthesized, and their photophysical properties were investigated. (Z)- and/or (E)-N-Styrylazinones (or azine) 4 were prepared from the corresponding heterocycles 1 and benzaldehyde (3) by four methods. The absorption maxima of (Z)- and/or (E)-4a – 4j were measured in four solvents. Their absorption maxima showed a moderate dependence upon solvents. The absorption maxima of (Z)-isomers were blue-shifted as compared the corresponding (E)-isomers. Emission maxima, fluorescence band half-widths, 0,0 transition energies, Stokes shifts, and quantum yields of (Z)- and/or (E)-4a, 4b, 4d, 4e and 4j were measured in organic solvents. The fluorescence spectra show moderate solvatochroism. The fluorescence properties of N-styrylheterocycles vary with every heterocycles.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 932-22-9
