Fabrication and Characterization of Ruthenium Complex-Vanadium Oxide Gel Hybrid Langmuir-Blodgett Films

摘要

Hybrid Langmuir-Blodgett films of an amphiphilic ruthenium tris-bipyridine complex(DC_nRu,n = 7,13 and 19)and vanadium oxide gel were fabricated and characterized.Langmuir monolayers of the amphiphilic molecules hybridized and stabilized with layered vanadium oxide were transferred onto a solid substrate as z-type multilayers with a transfer ratio close to unity.AFM observation revealed that the monolayer had a smooth surface with roughness of 5 nm over 1 mum~2.The hybrid monolayer of the vanadium oxide and DC_nRu showed photo-induced electron transfer to methyl viologens through the conduction band of the vanadium oxide.
