In the domain of supramolecular catalyst, non-covalent interactions are designed between the partners of the catalytic reaction in order to build catalysts with new functions or modify the catalytic performance of an existing catalyst.[4-5] We propose a new approach in which hydrogen-bonded supramolecular polymers, formed by means of non-covalent interactions between structurally-simple monomers, are used as a scaffold for catalysis. As a proof-of-concept, we performed asymmetric reactions by means of intrinsically achiral metal complexes positioned at the periphery of chiral assemblies. These chiral assemblies are formed either by means of 1,3,5-benzene tricarboxamide (BTA) chiral monomers[1] or mixture of chiral and achiral BTA monomers.[2],[3]
