Luminescence of Schiff-Bases in Solid-State
We prepared a series of schiff base compounds and investigated luminescence spectra of these compounds in the solid state. The schiff base compounds composed of phenyl rings with a hydroxyl group at an ortho position, imino groups and a butane or octane bridge show very strong luminescence in the solid state. For example, Msalbn (19) obtained from 2-hydroxy-acetophenone and 1,4-diaminobutane (excitation wavelength = 396 nm, emission wavelength = 496 nm, relative intensity = 38.02) and p-Me-anil (21) obtained from salicylaldehyde and p-toluidine (excitation wavelength = 396 nm, emission wavelength = 545.5 nm, relative intensity = 33.79) showed the strongest intensities in the luminescence. It was expected that luminescence properties of the compounds in the solid state were affected by molecular structure, intermolecular interaction and a type of the aggregation of molecules.
