Abstract
Zinc 3-hydroxymethyl-protopyropheophorbide-d derivatives 1, 2, and 3 possessing carbonyl group(s) at the 13/15-, 13-, and 15-positions, respectively, and 4 lacking the C=O group were prepared from naturally occurring chlorophyll-a. Zinc porphyrins 1 and 2 possessing the 13-C=O self-aggregated in an aqueous micellar solution, similarly to the self-aggregates of BChls-c/d/e in the main light-harvesting antenna systems of green photosynthetic bacteria, whereas 3 and 4 lacking the 13-C=O failed to make such well-ordered aggregates. These results indicated that both the presence of the C=O group and its situation at the 13-position were preferable for formation of the well-ordered J-aggregates.
