摘要：

Two series of novel diazo chromophores with tricyanofuran as acceptors and 3,4-disubstituted thiophene as bridges were prepared for second-order nonlinear optical applications. The chromophores were fully characterized using FT-IR, UV-vis, NMR and MS; thermal gravimetric analysis and differential scanning calorimetry revealed that the diazo-based chromophores have excellent thermal stability. The electrooptic coefficients (gamma(33)) were measured in the chromophores-doped poly(Bisphenol A Carbonate) films at the fundamental wavelength of 1315 nm, and the highest gamma(33) achieved was 30 pm/V.
