Two-dimensional poly(copper octathiotetraazaporphyrins), A and B, were prepared by treating 2,3,5,6-tetracyano-1,4-dithiin with Cu(AcAc)2 in vacuo or with CuCl2 in quinoline, resp. The polymers were characterized by elemental anal., TG-DTA, IR, UV, and fluorescence spectra. At room temperature in H2SO4 A fluoresces intensively at 300 ~ 520 nm under UV light. A semiconduction study yielded s298K = 2.29 ?10-6 W-1 cm-1, and 5.83 ?10-6 W-1 cm-1 for A and B, resp.
