The title polymers PNIPzS 4 and PCuPzS 4 were synthesized by reaction of phthalonitrile and 2,3,5,6‐tetracyano‐1,4‐dithiin with corresponding metal salt. Their structures and properties were characterized by associating the experimental results with MO and Cl calculations of the dimer molecule as model polymer in the ZINDO method. It has been found that the PNiPzS 4 (or PCuPzS 4 ) shows the semiconductivity at T < 253 K (or 260 K) and T > 278 K (or 286 K) and the conductivity increase with a hoist of temperature at 253 K (or 260 K) < T < 278 K (or 286 K). The conductivity σ of the PNiPzS 4 and PCuPzS 4 under pressure 13.73 MPa is 1.56×10 − 4 and 9.33×10 − 5 S/cm, respectively.
