2,9,16,23-Tetra-amino manganese(II) phthalocyanine (TAMnPc) was synthesized and characterized by mass spectrometry, infrared (IR) and electronic absorption spectrum. TAMnPc polymer films were prepared by spin-coating. The electronic absorption spectra of TAMnPc and its polymer films both exhibit an intense Q-band beyond 800 nm in the near-infrared region. The current-voltage characteristics of TAMnPc polymer films in the dark and under infrared irradiation were recorded. The electrical conductivity of films under infrared irradiation was obviously higher than that in the dark, indicating that TAMnPc has good photovoltaic response. © 2006 Elsevier B.V.
