structures are commonly encountered in natural and designed
systems. However, the bottom-up fabrication of regular geometric assemblies
with precise dimensional control, especially from soft materials,
poses an outstanding challenge in contemporary materials science and
chemistry. Herein, we present a general method for the preparation
of colloidally stable, hexagonal platelets via the formation of crystalline
inclusion complexes of tris-o-phenylenedioxycyclotriphosphazene
and block copolymers bearing interactive blocks. Dictated by the screw
dislocation growth of inclusion complexes, uniform hexagonal platelets
with precisely controllable dimensions can be prepared. This supramolecular
assembly approach is further utilized to produce concentric hexagonal
platelets via stepwise seeded growth from various inclusion complexes.
