Abstract

Effective photocurrent generation by visible light irradiation on hetero-deposited polymer Langmuir–Blodgett (LB) films containing tris(bipyridine) ruthenium(II) (Ru(bpy)₃²⁺) and anthracene derivatives was observed. The photocurrent amplification was found to be assisted by the photoinduced energy/electron transfer cascade, which consists of the interlayer triplet–triplet energy transfer process from photo-excited Ru(bpy)₃²⁺ to anthracene, and then electron transfer processes from the triplet anthracene to a viologen acceptor, from Ru(bpy)₃²⁺ to the oxidized anthracene and from the electrode to Ru(bpy)₃³⁺.
