Layered WO 3/4,4′-BPPOBp self assemble mulitlayers (SAMs) films have been fabricated by polyelectrolytes (PEs) approach. The SAMs films with well ordered superlattice structure and d space of 0.695nm and good photochromic property have been studied by employing UV visible, small angle XRD and XPS.

Key words: Superlttice film, Photochromic, WO3, 4,4-BPPOBp
