Scanning tunneling microscopy was used to characterize the formation of the cyclic trimers. Atomic force microscopy revealed the formation of nanopillars on a hydrophilized silica surface upon annealing from isotropic to room temperature.endiscotic molecules | hydrogen bonding | liquid crystals | scanning tunneling microscopy | supramolecules | trimersjournal article10.1055/a-2085-51252-s2.0-85166922775https://api.elsevier.com/content/abstract/scopus_id/85166922775
