Novel D-π-A'-π-A chromophores with quinoxaline cores as auxiliary acceptors and various donor moieties (aniline, carbazole, phenothiazine, tetrahydroquinoline) containing bulky tert-butyldimethylsilyloxy (TBDMSO) groups tricyanofuranyl (TCF) cyclohexylphenyl substituents were synthesized via eight- to nine-step procedures, their photo-physical thermal properties investigated. The values of the chromophores' first hyperpolarizabilities calculated in framework DFT at M06-2X/aug-cc-pVDZ...
Quantum chemical modeling in combination with vibrational and electronic absorption spectroscopy has delivered detailed information about supramolecular organization of azochromophore 4-amino-4′-nitroazobenzene (DO3), its solutions, blends poly(methyl methacrylate) (PMMA) polymer various concentrations. It is shown that the neat chromophore contains both antistacked forms hydrogen bonded associations "head-to-tail" type, while separate DO3 molecules dominate diluted solutions chloroform. In...
Novel D–π–A–π–A′ chromophores with different substituents in the donor moiety were synthesized and NLO coefficients for composite polymer materials doped them measured.
Second-order NLO characteristics of thin films based on model epoxy amine oligomers with 4-amino-4'-nitroazobenzene chromophore in the main chain, containing hydroxyl and methacryloyl groups, CFAO CFMAO, respectively, are determined. Synthesized polymers possess high content fragments have good film-forming properties, which allowed one to cast homogeneous 200-400 nm thickness. The presence reactive groups monomer units makes it possible use cross-linking polymer matrix preserve chromophores...
Quadratic nonlinear-optical characteristics of thin films based on methacrylic copolymers with chromophore-containing monomers incorporated at various concentrations are measured by Second Harmonic Generation technique. Optimal chromophores content is obtained to be about 17 mol%, rather high values coefficient, d33, up 60 pm/V, determined.
