The preparation of sub-5 nm ordered structures is very important to the development of today’s nanotechnology. Block molecules have the potential to form structures with significantly small characteristic dimensions. Herein...

Supramolecular liquid crystalline block copolymers prepared via hydrogen bonding exhibit hierarchical structures that can be tuned by varying the molar ratio of the discotic hydrogen-bonding acceptor to the block copolymer donor.

Temperature was adjusted to control the formation of inverse mesophases which can be used as templates to prepare inorganic materials.

Sub-5 nm ordered nanostructures including lamellar, double gyroid, and columnar phase are formed by a series of oligo(dimethylsiloxane) (ODMS)-based rod–coil liquid crystals with accurate molecular weights. Films with well-oriented line...

Obtaining nanoscale-ordered structures is important for the development of nanotechnology. We designed and synthesized a series of disk-cube triads containing one hexa-peri-hexabenzocoronene (HBC) and two polyhedral oligomeric silsesquioxane (POSS) moieties, HBC-2POSS. The two POSS units were linked via ester or amide bonds. With the amide linkage used, the hydrogen bonding that was introduced affected the balance between the π-π interaction of HBC cores and crystallization interaction of POSS units. Hierarchically ordered structures were obtained from HBC-2POSS triads owing to the synergistic effect of multiple secondary interactions: π-π interaction, hydrogen bonding, and crystallization interaction. As organic-inorganic hybrid materials, these HBC-2POSS triads are promising candidates for templates <10 nm.
