This contribution describes the synthesis of a pyridine-functionalized palladium(II) initiator via a simple two-step process and its use in the polymerization of a menthol-based isocyanide monomer, which results in a monotelechelic, static helical poly(isocyanide). The helical poly(isocyanide) was supramolecularly assembled with telechelic blocks of different secondary structures to form di- and multiblock copolymers. In addition, the facile syntheses of sheet-coil-helix and coil-sheet-helix covalent triblock copolymers will be presented. We show that the individual blocks contained within these supramolecular and covalent systems retain their secondary structures throughout the synthesis and assembly events. Future work will focus on the formation of triblock copolymers that include heterotelechelic helical middle blocks, as well as the incorporation of side chain functionalized helical blocks into supramolecular copolymers to further increase the complexity of our systems.
