Chiral recognition of L-and D-amino acid by porphyrin supramolecular aggregates
Molecules, 2018•mdpi.com
We report of the interactions between four amino acids lysine (Lys), arginine (Arg), histidine
(His), and phenylalanine (Phe) with the J-aggregates of the protonated 5, 10, 15, 20-tetrakis
(4-sulfonatophenyl)-porphyrin H4TPPS. Several aspects of these self-assembled systems
have been analyzed:(i) the chiral transfer process;(ii) the hierarchical effects leading to the
aggregates formation; and,(iii) the influence of the amino acid concentrations on both
transferring and storing chiral information. We have demonstrated that the efficient control on …

We report of the interactions between four amino acids lysine (Lys), arginine (Arg), histidine (His), and phenylalanine (Phe) with the J-aggregates of the protonated 5,10,15,20-tetrakis(4-sulfonatophenyl)-porphyrin H4TPPS. Several aspects of these self-assembled systems have been analyzed: (i) the chiral transfer process; (ii) the hierarchical effects leading to the aggregates formation; and, (iii) the influence of the amino acid concentrations on both transferring and storing chiral information. We have demonstrated that the efficient control on the J-aggregates chirality is obtained when all amino acids are tested and that the chirality transfer process is under hierarchical control. Finally, the chiral porphyrin aggregates obtained exhibit strong chiral inertia.
