Naphthalocyanine zinc (ZnNc) was synthesized and its molecular structure was characterized by FT-IR, elemental analysis, and MALDI-TOF mass spectrum. Cyclic voltammetry and optical absorption spectra confirmed that the extension of the conjugated system reduced the band gap of ZnNc compound. The composites of ZnNc with three electron acceptors of N,N’-di[2’-pyrimidinyl]-3,4,9,10-perylenetetracarboxylic diimide, C60, and 1-(3-methoxycarbonylpropyl)-1-phenyl[6,6]C61 were prepared by solution-blending, layer-by-layer evaporation, and spin-coating, respectively. The fluorescence quenching of the composites indicated that the photo-induced charge transfer occurred due to the energy level offset between the ZnNc and acceptor molecules.

Key words: naphthalocyanine zinc, charge transfer, fluorescence quenching, band gap
