摘要
The title compound E,E-1,4-bis[4?-(N,N-di-n-butylamino)styryl]-2,5-dimen- thoxybenzene (abbreviated to DBMB) has been synthesized by the wittig reaction of [(2,5- dimethoxy-1,4-phenylene)]bis(methylene)]bistriphenylphosphonium dichloride with 4-(N,N-di-n- butylamino)benzaldehyde. Its crystal structure was determined by a four-circle diffractometer. Crystal data: C40H56N2O2, Mr = 596.87, triclinic, space group P1, a = 0.9303(2), b = 0.9625(2), c = 1.0442(2) nm, α = 81.493(12), β = 78.387(12), γ = 87.876(11)o, V = 0.9057(4) nm3, Z = 1, Dc = 1.094 g/cm3, F(000) = 326, μ(MoKa) = 0.066 mm-1, the final R = 0.0925 and wR = 0.2092. The results reveal that the molecule is a completely reverse structure with fine symmetry and a conju- gated system.
