Self-assembly of Block copolymer (BCP) provides a robust method to construct a variety of micellar morphologies, ranging from spheres to vesicles. Crystallization-Driven Self-assembly (CDSA), one of the methods for the preparation of nano-objects, has attracted a great deal of interest due to its unique ability for dimensional control over 1D, 2D, and 3D nano-objects. Metallopolymers have been utilized in CDSA. I will present CDSA of cobaltocenium-containing block copolymers, poly(caprolactone)-<i>b</i>-poly(cobaltocenium amidoethyl methacrylate) (PCL-<i>b</i>-PCoAEMA), which can form 2D hexagonal platelet structures in protic solvents. By changing the composition of block copolymers, the block copolymers self-assembled into various two-dimensional platelets, from hexagons to diamonds.
