Summary: The study demonstrates a novel strategy for self-assembly of polymer end-tethered gold nanorods into tunable 2D arrays with the assistance of supramolecular hydrogen bonding. By rupturing the supramolecular matrix, well-ordered 2D arrays can be obtained, and the packing structure strongly depends on the molecular weight of the polymer ligands and the size of the GNRs. The resulting GNR arrays show anisotropic surface-enhanced Raman scattering performance, with vertically ordered arrays exhibiting significantly higher SERS signals compared to tilt ordered arrays.

Summary: Polysaccharide nanorods can be used as templates to form mesoporous materials. Ethanol cosuspensions containing the nanorods were electrospun to form hybrid organic-inorganic fibers, which exhibited mesoporosity after calcination. The fibers also showed additional microporosity due to the removal of the spinning polymer. The addition of a Ti4+ precursor led to the distribution of isolated and tetrahedral Ti units in the calcined fibers.
