  Novel fluorine-containing carbofunctional organosilicon monomers were synthesized: 3-pentafluorobenzylideneaminopropylethoxysilane (EtO)3Si(CH2)3N=CH-C6F5, N-3-methoxydiethoxysilylpropyltrifluoroacetamide (EtO)2(MeO)Si(CH2)3NHC(O)CF3, and 1,1,5-trihydrooctafluoroamyl N-3-triethoxysilylpropylaminopropanoate (EtO)3Si(CH2)3NH(CH2)2C(O)OCH2(CF2)3CHF2. Compositions for the formation of transparent thermally stable films were prepared from these monomers. The films have low absorbance intensity near 1550 nm, i.e., in the region of photosignal transmission of modern optical communication systems. The compositions can dissolve complexes with organofluorine ligands and produce transparent homogeneous films doped with rare-earth metals. The concentrations of the complexes in the matrices are 3.7–21.4 wt.% (metal concentrations are 0.6–3.7%). Fluorescence and fluorescence excitation spectra of the matrices and electronic absorption spectra of the doped films were studied.

  合成了新型含氟羧基有机硅单体：3-pentafluorobenzylideneaminopropylethoxysilane (EtO)3Si(CH2)3N=CH-C6F5, N-3-methoxydiethoxysilylpropyltrifluoroacetamide (EtO)2(MeO)Si(CH2)3NHC(O)CF3、和 1,1,5-三氢八氟酰胺基 N-3-三乙氧基硅丙基氨基丙酸酯 (EtO)3Si(CH2)3NH(CH2)2C(O)OCH2(CF2)3CHF2。利用这些单体制备了透明热稳定薄膜。这些薄膜在 1550 纳米附近（即现代光通信系统的光信号传输区域）具有较低的吸光强度。这些成分可以溶解带有有机氟配体的络合物，并生成掺杂稀土金属的透明均质薄膜。基质中络合物的浓度为 3.7-21.4 重量%（金属浓度为 0.6-3.7%）。研究了基质的荧光和荧光激发光谱以及掺杂薄膜的电子吸收光谱。
