摘要
Abstract
With phenyl as the center,a new D-π-A star-shaped molecule (Y) was designed and synthesized by introducing two electron-donors,(D) unit triphenylamine and electron-accepting (A) unit phenanthroimidazole with Suzuki coupling,and its structure has been characterized by NMR, ESI-MS and elemental analysis. The third order nonlinear optical properties of the compound Y has been studied systematically through UV-Vis absorption spectroscopy,fluorescence spectroscopy,the fluorescence quantum yield,theoretical calculation and Z-scan technology. The results showed that the fluorescence quantum yield (ϕ) is up to 0.77,the two-photon absorption cross section (σ2) is 120GM, and the third order nonlinear refractive index (n2) is 9.0×10−7cm2/GW,which provides a new idea for the design of molecular with good nonlinear optical properties.关键词
