A much wider range of geometrical patterns can be made with multiblock copolymers compared to conventional diblock copolymers. We use a metal-containing triblock terpolymer in order to produce various pattern morphologies including co-axial prisms which form Archimedean tiling patterns and square symmetry patterns. These materials offer an expanded options for pattern generation for nanolithography and making functional nanostructures with highly controlled 3D architectures.
