Structure peculiarities of interfacial layer formed from copper complexes with covalently bonded to SiO_2 polydentate amines

摘要

The method that allows to obtain two-dimensioinal low-density matrixes with lattice-type distribution of bonded functional groups was developed. Influence of immobilised molecule size and its binding properties to the interfacial layer properties was evaluated from results of reaction between Cu(BF_4)_2.2H_2O solution in dimethylformamide with bonded to SiO_2 silanes with general formula (RO)_3Si-(CH_2)_3NH(CH_2CH_2NH_nH, where n=0-2. By varying of synthetic conditions matrixes with average distant between neighbour group was from 0.8 to 1.55 nm. The results were supported by EPR and optical spectra.
