Ordered structures and sub-5 nm line patterns from rod–coil hybrids containing oligo(dimethylsiloxane)

Abstract

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...

Ordered structure constructed from C2-symmetric hexa-peri-hexabenzocoronene linked with oligo(dimethylsiloxane)

“…29,30 We also linked ODMS flexible chains to both ends of a rod-shaped LC core, and different nanophase-separated structures including lamellar, double gyroid, rectangular columnar, and hexagonal columnar (Col h ) phases were formed. 31 Therefore, the self-assembly of block molecules is feasible to produce sub-10-nm or even sub-5nm structures.…”

Highly Ordered Supramolecular Materials of Phase‐Separated Block Molecules for Long‐Range Exciton Transport

“…[3] Recently, oligodimethylsiloxane (oDMS) side chains have been attached to various aromatic cores to create highly ordered structures at the nanoscale. [16][17][18][19][20][21][22] In one such example, domains of millimeter-sized aligned 2D crystalline sheets could be obtained by slow cooling from their melt. [16] For this purpose, oDMS blocks of discrete length are covalently linked to diphenylanthracene (DPA).…”

Catalytic assembly of symmetric diblock copolymers in a thin film: a dissipative particle dynamics simulation study

“…[4][5][6][7] Moreover, the self-assembled structure in a thin film can be transferred onto semiconductors to manufacture microelectronic devices with a nanoscale structure. [8][9][10] An ''ideal'' assembly enables the system become thermodynamically stable, leading to the formation of a welldefined structure. However, often the assembly falls into a metastable state, yielding unexpected structures such as defects and dislocations.…”
