Experimental Section
The porphycenes were reduced chemically with sodium metal under
high-vacuum conditions? Tetrahydrofuran (THF) dried over a Na/K
alloy was used as a solvent. The porphycene concentration was about 5
X IO4 M. The radicals were stable over at least several weeks when
stored at -27 "C. The anion radicals of HIPCl were also generated by
potentiostatically controlled electrolysis in THF using tetra-n-butyl-
