Luminescent Properties of Photocured Acrylic Polymer Matrices Containing an Organic Fluorescent Dyad

Abstract

The luminescent properties of an organic dyad that combines two different luminophores, hydroxy-substituted 2,4,5-triarylimidazole and 8-azomethine-7-hydroxycoumarin, in its molecule have been studied in seventeen polymer matrices obtained by photocuring, which are represented by linear poly(meth)acrylates differing in the amount of hydroxyl groups and acrylic network polymers differing in the nature of crosslinking oligomeric blocks. The dependence of the luminescent properties of materials on the wavelength of excitation light, as well as on the presence and amount of hydroxyl groups in polymers; the presence of urethane groups, ether bonds, and aromatic moieties (individually or in combination); and flexibility and conditional polarity of the matrix, has been established.
