摘要 A hemicyanine dye containing an amphiphilic rare earth complex anion 4-[(4-N,N’-(diethyl amino) phenyl) ethenyl]-1-hexadecyl-pyridinnium-Tri (1-phenyl-3-methylbeen designed, synthesized and characterized. Its floating monolayer film was spread bya dilute cliloroform solution onto the pure water subphase by using a NIMA TechnologyLB Though at room temperature. The π-A isotherm shows that the film formation property is improved and the multilayer films are homogeneous. The molecular second orderhyperpolarizability(β) is evaluated to be 5.4× 10-28e.s.u. which is one of largest SHG material reported.
