Synthesis of unsymmetrical 4-oxo-2-vinyl-4H-chromene-3-carbonitrile dyes via Knoevenagel reaction

New 4-oxo-2-vinyl-4H-chromene-3-carbonitrile derivatives have been synthesized by the Knoevenagel reaction of 2-methyl-4-oxo-4H-chromene-3-carbonitrile with aromatic and heteroaromatic aldehydes. Spectral properties of the obtained compounds have been studied.

Thermally stable nonlinear optical polymers based on polyimides substituted with chromophores containing julolidine moiety

We designed and synthesized a NLO chromophore adopting the concept of shape modification as well as possessing high thermal stability. The chromophore was featured by a phenylene ring as a conjugation bridge, a bulky alkyl chain attached on the side of the conjugation bridge, and julolidine moiety as an electron donor. The NLO chromophore was attached to the polyimide as a side chain, resulting in thermally durable NLO polymers. On set decomposition temperature of the NLO chromophore was measured 330°C in TGA analysis. The NLO polymer exhibited high glass transition temperature of 150°C and was thermally stable up to 250°C. The polymer was quite soluble in common solvents and produced an optical quality film by spin-coating. The electro-optic coefficient of the film was measured using 1.55 μm laser source, giving as high as 30 pm/V at the poling condition of 150°C and 1 MV/cm.
