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

The structure of mixed TC 16 PyP(4)/AnQ LB films was characterized by π A isotherms, UV Vis absorption spectra and low angle X ray diffraction(LAXD). The experimental results indicate that the TC 16 PyP(4)/AnQ mixture can form a stable monolayer on the air/water interface. Most AnQ molecules are incorporated into the cavities between the long alkyl chains of TC 16 PyP(4) molecules in the mixed monolayer and LB films. Mixed TC 16 PyP(4)/AnQ monolayer can be transferred to the substrates. TC 16 PyP(4)/AnQ LB films have a good stability and periodicity. [WT5HZ]展开更多
