Peculiarities of the Manifestation of Multiple Luminescence of Organic Compounds in Photocured Acrylic Polymers

The influence of the nature of linear acrylic polymers differing in the concentration of hydroxyl groups on the spectral-luminescent properties of a hybrid compound, the molecule of which combines two different luminophore fragments, namely, hydroxy-substituted 2,4,5-triarylimidazole and 8-azomethine-7-hydroxycoumarin, and model compounds corresponding to these fragments, is studied. The optimum conditions for the preparation of acrylic polymers containing the luminophores under study by photocuring are selected. The dependence of the luminescent properties of the materials on the number of hydroxyl groups is established.
