To synthesize novel non-planar porphyrin derivatives, we have conducted ring-fused reactions with peripheral substituents of porphyrin derivatives. As results, we have obtained four kinds of novel ring-fused porphyrin derivatives. The ring-fused porphyrins possessed smaller HOMO-LUMO gaps due to the extended a-conjugation of the porphyrins, and consequently, red-shifted absorption bands were observed in the UV-vis spectra and negatively shifted oxidation potentials and positively shifted reduction potentials were obtained in the electrochemical measurements
