(a) X-band cw-EPR spectra of the radical cations of l-P1 to l-P6, c-P6, c-P6·T6 and t-P12·(T6)2 recorded at 298 and 100 K in toluene-d8/THF-d8/CD2Cl2 with oxidation by thianthrenium hexachloroantimonate. The spectra at 100 K are compared to the corresponding room temperature spectra shown in the background. (b) Peak-to-peak linewidths of the room temperature EPR spectra plotted as a function of the reciprocal square root of the number of porphyrin units. The gray line is the curve for eq 2.
