The luminescent properties of photocured aliphatic and aromatic network polycarbonate methacrylates containing organic fluorescent dyad have been studied. The dyad molecule includes two photosensitive fragments – tetraarylimidazole with a hydroxy group and azomethinocoumarin, in each of which excited state intramolecular proton transfer occurs, which leads to the appearance of two emissions - blue and green. It was established that the ratio of the intensities of these emissions depends on the excitation wavelength, as well as on the length, flexibility and polarity of the matrix oligomeric bridges.
