The spatial arrangement of chlorophyll and bacteriochlorophyll dyes enables pivotal functions in the light-harvesting systems of purple and green bacteria which contain a large number of these chromophores organized in cyclic arrays or tubular architectures by non-covalent interactions. During the last years, we have intensively investigated the self-assembly behavior of semisynthetic zinc chlorin dyes into metallosupramolecular polymers which is directed by oxygen-zinc(II) coordination, pi-pi-stacking and in some cases by additional hydrogen-bonding interactions. The focus of this contribution will be devoted on our most recent studies on the self-assembly mechanism and the elucidation of the charge transport properties of self-assembled zinc chlorins.
