Abstract A synthetic route for the preparation of covalently-linked porphyrin-quinone and metalloporphyrin-quinone complexes as models for the phototrap in bacterial photosynthesis is described. 5-(4-Carboxyphenyl)-10, 15, 20-tritolylporphyrin, prepared by a mixed aldehyde approach, was attached to a benzoquinone center with a propanediol bridge by means of ester linkages. The starting point for the benzoquinone moiety was 2, ...
