| Abstract: | Twenty Schiff bases are prepared from four kinds of benzaldehydes and aromatic amines.The synthesized compounds are purified by recrystallization.Decomposition and decomposition prevention of Schiff bases are discussed.UV absorption spectrum and SHG effect of the twenty synthesized compounds are measured.Seven compounds show SHG activity.Two of them have SHG effect stronger than urea.The effects of substituents on λ max ,Δλ 1/2 max and SHG of Schiff bases are discussed also. \ \ |
