Natural proteins are linear macromolecules constituted of amino acids that have the ability to fold into highly organized structures. These nanometric assemblies are crucial and they are at the origin of the essential functions of life. Synthetic polypeptides polymers are simplified proteins analogues that are made of blocks of amino acids. They are perfect materials 1) to design protein mimics able to reproduce some properties of natural proteins, 2) to create innovative polymeric structures for materials science applications. In particular, polypeptide polymers can adopt natural protein secondary structures such as alpha-helix or beta-sheets and this unique feature is, in polymer chemistry, at the origin of intriguing physico-chemical properties. In this context, the use of coordination chemistry as a way to tune the physico-chemistry of synthetic polypeptides polymers has been poorly explored, even if coordination chemistry represents nowadays an important tool to design advanced materials with enhanced properties. I want to show that thanks to reversible coordination chemistry, synthetic polypeptides polymers can behave as metal responsive polymeric systems. The aim of this current work is the design of new smart metallopolypeptide that will find uses in (bio)diagnosis and in catalysis.
