Abstract
N,N'-etheno-bridged porphycenes have been synthesized in good yields b y the reaction of Co(II) porphycenes with acetylenes in the presence o f FeCl3. The etheno-bridge was introduced predominantly between the ad jacent two nitrogens in the dipyrrylethene side rather than the dipyrr ole side. These porphycenes are reduced at potentials more positive by ca. 0.5 V than those of the corresponding N,N'-etheno-bridged porphyr in analogues. (C) 1997 Elsevier Science Ltd.
