Self-assembled inorganic/organic composite superlattice thin films with photochromic properties
A multicomposite WO3/4,4'-BPPOBp self-assembled multilayer (SAM) film was fabricated by the consecutive self-assembly of WO, and 4,4'-BPPOBp on 3-aminopropyl-triethyoxysilane (APS) modified quartz or silicon substrate by a polyelectrolyte (PE) approach. A well-ordered superlattice structure, d-spacing 0.694 nm, was identified by X-ray diffraction and X-ray reflection techniques. The SAM film shows fine photochromic properties.
