High Efficient Photochromic WO3 polymer/1,10 DAD Self assembly Films Modified by Organic Molecules

A novel high efficient photochromic self assembly multilayered film has been fabricat ed from WO3 and 1,10 DAD solution using molecular deposition technique.The dependence of photochromic behavior on aggregation of WO3 in the WO3 polymer/1,10 DAD self assembly film was discussed in comparison with WO3/ 4,4'-BAMBp system.The results clearly show that organic molecules determine the charge density of the substrate,then affect the assembled structure of inorganic precursor and the stablility of the photo induced charge transfer complexes,and thus manipulate the structure and the photochromic properties of the films.
