Abstract
Three new silicon- and fluorine-containing ligands, namely bis(dimethylamido)(3-triethoxysilylpropylamido)phosphate O=P(NMe2)2NHCH2CH2CH2Si(OEt)3, diphenyl(3-triethoxysilylpropylamido)phosphate O=P(OPh)2NHCH2CH2CH2Si(OEt)3, and tris(3,3,3-trifluoropropyl)phosphine oxide O=P(CH2CH2CF3)3 are synthesized. The erbium and ytterbium complexes with amine, phosphate, and phosphine oxide ligands Ln(NH2R)3Cl3, Ln[O=P(NMe2)2NHR]3Cl3, Ln[O=P(OPh)2NHR]3Cl3 (R=CH2CH2CH2Si(OEt)3), Ln[O=P(OPh)3]3Cl3, Ln[O=P(CH2CH2CF3)3]3Cl3 are produced and their electronic absorption spectra and photoluminescence spectra are studied. The silicon-containing compounds form transparent thermostable films on silicate glass or quartz surface.
