Stepwise Construction of Supramolecular A<sub>2</sub>B<sub>4</sub>‐Type Miktoarm Star Copolymers with a Cobalt Phthalocyanine Core
Supramolecular interactions between polymers play a crucial role in the construction of three-dimensional polymer structures with unique physical and chemical properties. In this study, we have fabricated a novel supramolecular miktoarm star copolymer (μ-star) with a cobalt(II) phthalocyanine (CoPc) core using metal-ligand coordination. Axial coordination of the terminal pyridyl group of poly(methyl methacrylate) with the CoPc core of four-armed star-shaped polystyrene provided AB<sub>4</sub>- and A<sub>2</sub>B<sub>4</sub>-type μ-stars through stepwise complexation. The spin-coated polymer films from mixed solutions of CoPcPS<sub>4</sub> and pyPMMA in 1 : 1 or 1 : 2 mass ratios exhibited phase-separated nanodomains with smooth surfaces. Supramolecular interactions in polymer systems provide a unique topology to polymers and affect their bulk morphology.
