Abstract:

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-methyl-4-benzyol-pyrazolone-5)-(4-dodeconoyl-1-phenyl-3-methyl-pyrozone-5) dysprosium been designed, synthesized and characterized. Its floating monolayer film was spread by a dilute chloroform solution onto the pure water subphase by using a NIMA Technology LB 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 order hyperpolarizability(β) is evaluated to be 5.4×10-28e.s.u. which is one of largest SHG material reported.
