Summary:This paper describes the synthesis and characterization of a novel class of hydrogen-bonding oligo(dimethylsiloxane)-based thermotropic liquid crystals (LCs), with which polymeric supramolecules were obtained with glassy smectic and columnar sub-5 nm features when combined with poly(4-vinylpyridine) homopolymer or poly(styrene)- b -poly(4-vinylpyridine) block copolymer (BCP). The hierarchical self-assembly afforded by the LC/BCP complexes further resulted in the vertical orientation of the LC features in thin films. Polymeric supramolecules were prepared using hydrogen-bonding oligo(dimethylsiloxane)-based liquid crystals and poly(4-vinylpyridine) homopolymer or poly(styrene)- b -poly(4-vinylpyridine) block copolymer. These materials form glassy, hybrid organic/inorganic thin films with sub-5 nm features.
