Abstract:

It has been demonstrated that organic second-order nonlinear chromophore, with hetero-aromatic ring as the conjugating bridge, has large hyperpolarizability. In this work, with the aim of studying the hyperpolarizability influenced by the length of conjugating bridge, a novel organic non-linear optics(NLO) chromophore MF3C containing bifuran conjugating bridge, tricyanofuran as electron acceptor and dimethylamine as donor was synthesized through Wittig reactions and Vilsmeier reactions. The new chromophore was characte-rized by FTIR, 1H NMR and elemental analysis. Thermogravimetric analysis(TGA) test revealed that the decomposition temperature(Td) of the molecular was up to 228℃. Solvatochloroform method was used to calculate the hyperpolarizability(μgβ). We got the μgβ value of MF3C led to 5.9×10-44 esu at 1064 nm. With good thermal stability and large hyperpolarizability simultaneously, the chromophore shows great potential applications in electro-optic devices.
