Abstract

The luminescence polarization properties of new recording media obtained by directed synthesis—disulfochlorides of luminescent dyes (homologues of 1,7-diamino-3,9-dihydrodibenzo-[1,2,3de:4,5,6- d'e']diquinoline-2.8-dione (1,5-diaminoanthradipyridone) series), with the general structure (ClSO2)2-1,5-di-AAP-di-R—are investigated. Polarized photoluminescence spectra are recorded, and spectral dependences of the degree of anisotropy of phosphor on its chemical structure at different acidities of the medium are plotted.
