Abstract
The reactions of FeCl3, AlCl3 and ZrCl4 dissolved in nitromethane with (CH)X result in the formation of p-type conducting polymers. Of all three new materials FeCl3 doped (CH)X exhibits the highest conductivity and stability in air. EPR shows a broad line which is consistent with high spin Fe2+ complex formed in the reaction. AlCl3 doped samples are also highly conducting but very unstable in air. The EPR spectrum is only slightly Dysonian probably due to the partial reaction of the dopant with traces of moisture. ZrCl4 dopes (CH)X to significantly lower conductivity giving a weak totally symmetric EPR signal.Keywords
