title: Multiply-fused porphyrins--effects of extended π-conjugation on the optical and electrochemical properties.
abstract: A novel quadruply-fused porphyrin has been synthesized with a facilely prepared precursor in a high yield. A detailed comparison of the physical properties of a series of fused porphyrins revealed remarkable effects of the ring fusion on lowering LUMO levels rather than HOMO levels.
