“…They are also widely used for the manufacturing of optical products, coatings, especially in the conditions of radiation and photoinitiation [4,7]. Their application in stereolithography is described, for example, the layer-by-layer manufacture of parts from liquid oligomers, including oligocarbonate methacrylate, using an excimer XeCl laser (λ = 308 nm) [8]. Now photopolymerization processes such as direct laser writing, three-dimentional micromashining, optical elements fabrication, data recording and storage are widely distributed and they all use oligocarbonate methacrylates compositions [9,10].…”

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.

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 hydroxyl group and azomethinocoumarin—in each of which excited state intramolecular proton transfer (ESIPT) occurs, leading to the appearance of two emissions: blue (450 nm) and green (535 nm). It was established that the ratio of the intensities of these emissions depends very significantly on the excitation wavelength, as well as on the length, flexibility and polarity of the matrix oligomeric bridges.
