It was demonstrated by structural modeling that the long-wave band in the UV spectra of azomethine derivatives of o-methoxybenzaldehyde is associated with transfer of electron density in the aldehyde fragment. The development of luminescence in the azomethines is due to the planarity of the molecule, a consequence of which is exclusion of the quenching fluorescence of the n-¶ interaction and a sufficient magnitude of the energy gap between the n,¶* and ¶,¶* states. In the investigated series 4-(2-methoxybenzylideneamino)-1,2,4-triazole molecules have such properties. |
