The obtained dyes meet demands: to absorb light intensevely in the spectral region 390-410 nm, to dissolve in nonpolar solvents aiming preparation of thin films by centrifugation together with polymer or to evaporate in vacuum without decomposition. The obtained dyes have a chemical constitution that promotes homogeneity of structure of their films and keeping the last one during some time. We developed synthesis of wide series of conjugated donor-acceptor systems: nullmethine merocyanines pyrane and dihydropyridine derivatives, bases of -cyano- and 4-amino- substituted or 4-alkoxy- substituted styryls, heterocyclic chalcone analogues, heterocyclic substituted pyrazolines. Absorption of 85-90% could be achieved for films containing 1-2% of dyes. Several new chromophores, which belong to the conjugated system class characterized by intensive absorption at wavelength 405 nm, evaporable in vacuum without decomposition, have been determined. The regularities connecting the chemical structure of new merocyanines and styryl bases with their spectral properties (position of absorption maxuma, absorption intensity, and so on) have been established. At several compounds, the technology of superhigh density laser recording on the thin nanocomposite dye films for modern information systems was proposed. It was found that new dyes can be applied for optical recording of information by termolitography method. Such optical recording mediums will be used in libraries, medicine and other fields of society informatization.
