Abstract

Abstract: Four novel rare earth coordination compounds,(E)-hexadecyl-4-(2,4-dimethylaminophenyl)ethenyl pyridinium tetrakis-(1-phenyl-3-methyl-4-benzoylpyrazolonato)lanthanide(Ⅲ)(La, Nd, Dy, Yb) have been synthesized and characterized by elementary analysis, UV-Vis, IR,¹HNMR,TG-DTA analysis,X-ray photoelectron specroscopy,X-ray powder diffraction and molar conductivity. The comparison of the surface pressure-area isotherms of the complexes with that of hemicyanine, bromide is made. The better Langmuir film-forming properties of the metal complexes are obtained. Preliminary result of second harmonic generation (SHG) from monolayer film of the dysprosium complex is reported.

Key words: Lanthanide coordination compound, Hemicyanine, Langmuir-Blodgett film, Second-harmonic generation
