A series of H2, Mg, VO, Co, Ni, Cu, Zn, Pd, Pt, Bi, and Pb 4, 4, 4, 4-tetracumylpenoxy phthalocyanine, MPcXZ4, was synthesized. By vapor pressure osometry measurements of toluene solutions at 65 C, all MpcX4 compounds were dimeric complexes except PbPcX4 which is monomeric and Cu, Ni, Pd and PtPcX4 which form larger complexes ranging from 2.7 to 4.1 molecular units. Each MPcX4 forms a stable Langmuir-Blodgett monolayer to film pressures of 20 mNm and force-area curves indicate a dense packing of phthalocyanine units with molecular areas increasing with complex size.
