Synthesis, conductivity and photosensitivity of 2-D conjugated polymers of metalporphyrazine with sulfur bridges

The title polymers PMS8Pz, M=MnII, FeII, CoII, NiII, CuII, ZnII, were synthesized by reaction of 2, 3, 5, 6-tetracyano-1, 4-dithiin with corresponding metal salts, respectively. The structure and properties of these polymers were characterized by elemental analysis, transmission electron microscope, DTA, IR, UV-Vis, fluorescence and EPR spectra. It has been found that these conjugated polymers have the property of intrinsic semiconductor. The conductivity σ298K of these polymers is in the range of 10−9≈10−3 S·cm−1 under pressure 10.63 MPa and incrementals in the metal order Mn<Co<Fe<Zn<Cu<Ni. The photosensitivity of the MS8Pz to the CdS-PVA films is incrementals in the metal order Zn<Mn<Co<Fe<Cu<Ni.
