Stepwise Construction of Supramolecular A2B4-type Miktoarm Star Copolymers with a Cobalt Phthalocyanine Core.
Supramolecular interaction between polymers has been utilized for constructing three-dimensional polymer structures with unique physical and chemical properties. In this study, we demonstrated a novel supramolecular miktoarm star-shaped copolymer with a cobalt(II) phthalocyanine (CoPc) core using metal-ligand coordination. Axial coordination of the terminal pyridyl group of poly(methyl methacrylate) to the CoPc core of 4-armed star-shaped polystyrene provided AB4- and A2B4-type µ-stars by stepwise complexation. The spin-coated polymer films from the mixed solutions of CoPcPS4 and pyPMMA in a 1:1 or 1:2 mass ratio showed phase-separated nanodomains with smooth surfaces. Superamolecular interactions in polymer systems provide a unique topology for polymers and affect their bulk morphology.
