The silicon gel initiator was prepared by self-assemble. Utilizing these modified silicon gel as the substrate, a kind of novel inorganic-organic hybrid material with the polymer metal complex was synthesized. The result of ESR indicates that the inorganic/organic hybrid material with the polymer metal complex based on silicon gel possesses well paramagnetis.展开更多

The LB films of two amphiphilic complexes, DODA/PW 9Mo 3O 40 and DODA/PW 6Mo 6O 40 , were prepared from 12 tungstomolybdophosphheteropolyacid with dimethyldioctadecylammonium and their properties and the structure wer...The LB films of two amphiphilic complexes, DODA/PW 9Mo 3O 40 and DODA/PW 6Mo 6O 40 , were prepared from 12 tungstomolybdophosphheteropolyacid with dimethyldioctadecylammonium and their properties and the structure were characterized by UV Vis absorption spectra, fluorescence spectra, low angle X ray diffraction(LAXD) and π A isotherms curves. The results showed that the molecular areas for each comlex are 0.56 nm 2, and all of them could form an idealized structure with a stability of the Langmuir Blodgetl films.展开更多
