โœฆ Synopsis

The synthesis of two cyclic porphyrin dimers is reported. In each case the porphyrins are cotmected by a rigid butadiyne link, and a flexible alkyl chain tc~ter.

The length of this t~her controls both the porphyrin-porphyrin distance, and porphyrin-porphyrin geomet~. It is hoped that the e~tra fl~ibility designed within these molecules will enable them to act as general catalytic hosts for future study.

Methodology for synthesis of symmetrical or unsymmetrical porphyrin dimers linked at the meso positions with phenyl or stilbene functionalities is reported; 5-porphyrinyl-dipyrromethanes are key intermediates in this approach.
