摘要
A novel high- efficient photochromic self- assembly multilayered film has been fabricated 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.
