High resolution images of individual molecules of the liquid crystalline material adsorbed on a photopolymer treated transparent conducting (indium oxide coated) glass plate have been obtained with a scanning tunneling microscope (STM). The ultrathin layer of the photopolymer poly‐vinyl‐4‐methoxy‐cinnamate (PVMC) on the conducting glass plate was deposited by the bulk induced alignment technique reported earlier [S. C. Jain and H.‐S. Kitzerow, Appl. Phys. Lett. 64, 2946 (1994)]. The liquid crystal molecules exhibit a positional order, in addition to a high degree of orientational order of the bulk nematic. This surface ordering of the nematic liquid crystal at the polymer interface is quite different from the ordering observed on graphite and molybdenum disulphide substrates. A small ensemble of molecules show antiparallel ordering of the cyano‐phenyl‐cyclo‐hexane molecules in agreement with the calculations of Schadt et al. [Liq. Cryst. 5, 293 (1989)].
