An easy and versatile solution-based route for the synthesis of a new phthalocyanine-based light-harvesting material PCIGS [Cu₂(tBu₄PcGa)(tBu₄PcIn)S₂TPP₂] is described. This material is preparedthrough a one-pot reaction of tBu₄PcM-Cl (M = Ga, In), CuI, and [(CH₃)₃Si]₂S in the presence of triphenylphosphine. In contrast to the dilute solution, the linear absorption coefficient of PCIGS complex in thesolid state (₀ = 145.35 cm^-1) is about 150 times greater than the dilute solution (₀ = 0.95 cm^-1) underthe conditions of the study. The molecular structure of this material is proposed on the basis of theextended X-ray absorption fine structure spectroscopy.
