AM1 type semiempirical quantum chemical calculations were carried out on model poly(p-phenylene), PPP, structures having nine phenylene units and an additional p-cyclophane moiety. The calculations were also extended to their monovalent radical cations. The position-dependent effect of cyclophane system (through bond and/or space) was investigated for each set of systems.
