Preparation of Peapod Polymer via the Supramolecular Chain Formation by Tris(spiroborate) Twin Bowl

Successive guest-containing tubular polymer was prepared by the olefin metathesis polymerization of tris­(spiroborate) twin bowl after the formation of supramolecular polymer. The cationic iridium­(III) complexes were topologically fixed inside the polymer to form a peapod-like structure. The polymer was evaluated by SEC, ICP-AES, and DLS analyses, and string-like structures were found in the AFM observation of the peapod polymer.
