Tuning the supramolecular chirality of one- and two-dimensional aggregates with the number of stereogenic centers in the component porphyrins

A synthetic strategy was developed to perform synthesis of porphyrins containing between one and four stereogenic centers, such that their molecular weights vary only as a result of methyl groups which give the chiral forms. The self-assembly and chiral structure of the aggregates of porphyrin molecules are observed to be significantly influenced by the number of stereogenic centers.
