摘要

Multilayer films of poly( 3,4-(3',3'-dithienyloxy) propyltrimethylammonium bromide) ( P34TOPA) and 11-mercaptoundecanonate ( MUA) capped gold nanoparticles ( GNPs) have been fabricated by layer-by-layer ( LBL) deposition. These films exhibit enhanced photoresponsive properties in comparison with those of a monolayer of P34TOPA and MUA capped GNPs. The photocurrent densities increased linearly with the bilayer number ( 1-10) of the multilayer films, indicating a sufficient charge separation and transportation. The size effect of gold nanoparticles on the photoresponsive properties of the multilayer films is also discussed.
