The self-assembly of amphiphilic metallo-supramolecular A-b-B-b-A triblock copolymers containing a B block formed from a bisfunctional terpyridine monomer and an A block based on a monofunctional terpyridine polymer is described. These polymers have been prepared by a polycondensation approach, based on metal–ligand complexation, in which the molecular weight of the central B block has been controlled by the addition of a monofunctional chain-stopper A. Details for the preparation of the A-b-B-b-A triblock copolymers based on the tpy₂Ni(II), tpy₂Fe(II), and tpy₂Co(II) connectivity are given. The influence of the different binding strength of Ni(II), Fe(II), and Co(II) metal ions with terpyridine ligands on the metallo-polycondensation reaction and on the micellization behavior of those materials was studied. Micelles of the obtained block copolymers were prepared and studied by DLS and cryo-TEM.
