| مستخلص: |
D--π--A chromophores with indole donor and tricyanofuranyl acceptor moieties connected by vinylene and divinyl quinoxalinone π-conjugated bridges have been sythesized and their linear and nonlinear optical properties were studied. Chromophores exibit intramolecular charge-transfer (ICT) absorption band in the visible region, positive solvatochromism, and are transparent at 850 nm. The indole-based chromophore with divinylquinoxalinone π-conjugation bridge shows large µβ value (~13000•10-48esu); the incorporation of the vinyl quinoxalinone unit leads to a significant increase in the values of the first hyperpolarizability.
