A novel octupolar chromophore with 1,3,5-triazine as core,2,7-divinylene-9,9-dimethylfluorene as extended π-conjugated bridge,triarylamine as the electron-donating end-groups was successfully synthesized and characterized.Their linear photo-physical and two-photon absorption (TPA) properties were investigated by UV absorption,excited fluorescence (SPEF) spectra and nonlinear transmission method,respectively.The absorption cut-off of the chromophore is below 520 nm and it has stronger fluorescence emission in a nonpolar solvent.In addition,the chromophore exhibits larger TPA cross-section (226.0 GM) in the femtosecond regime at 800 nm.
