4,4’-Bis(o-methoxylstyryl)biphenyl compound was synthesized by a Wittig-Homer reaction. Its crystal structure was determined by X-ray diffraction method. The one-photon optical physical properties of the title compound in different solvents were investigated carefully and the one-photon fluorescence quantum yield was determined. Pumped by 700～820 nm fs laser, the title compound exhibited strong two-photon up-converted blue fluorescence in N,N-dimethylformamide, and two-photon absorption cross-sections 155 GM at 700 nm laser.

Key words: styrylbiphenyl compound, crystal structure, two-photon absorbtion
