摘要：

Perfluoroadipic bis(trialkoxysilylpropyl)amide was synthesized as a mixture of five com- pounds with the general formula (EtO)n(MeO) 3-n Si(CH2)3NHC(O)(CF2) 4C(O)NH(CH2)3 Si(OMe)n(OEt) 3-n (1, n = 1, 2). Hydrolysis of this product by a specified amount of water (1 : 4) gave oligomers EtO[(HO)(EtO)Si(CH2) 3NH(O)C(CF2)4C(O)NH(CH2) 3Si(OEt)2O]nH (n = 7-9). From oligomer solutions, transparent glassy thermally stable films were obtained. The film material was studied by IR spectroscopy, atomic force microscopy, transmission electron mi- croscopy, and powder X-ray diffraction. Compound 1 and oligomers can efficiently solvate lanthanide diketonate complexes. They displace water from the metal coordination sphere, and this water is then spent for hydrolysis of trialkoxysilyl groups. The luminescence intensity of matrix films based on the oligomers depends on the concentration of lanthanide complexes and is very low at λexc = 330 nm, whereas the luminescence intensity of the Eu3+ cation is very high. © 2010 Springer Science+Business Media, Inc.
