Langmuir-Blodgett- Kuhn (LBK) multilayers of azobenzene polymeric containing polyamic acid were fabricated onto fused silica substrates and gold-coated optical glass slides were fabricated. UV-Vis spectroscopy was employed to investigate the optical response of multilayers films. The thickness of monoand multilayers were measured by use of SPR spectroscopy. UV-Vis and SPR spectroscopy results show that the thickness of PAA6B monolayer is 2.5 nm. Photoisomerization studies showed the excellent reversibility of the trans–cis and cis–trans isomerization reactions of the azobenzene sidegroups within the multilayer structures. Further, these films were found to be suitable for all-optical switching devices based on liquid crystal material.
