1. A method of patterning a surface of a solid on a molecular scale, comprising:

  • providing a reactive solid having a surface;

    forming a pattern of adsorbed molecules at sites on said surface of said reactive solid by providing a plurality of preselected molecules and exposing said surface to said preselected molecules;

    exposing said surface to an effective blocking agent subsequent to exposing said surface to said preselected molecules to militate against surface diffusion of said adsorbed molecules; and

    forming an imprinted pattern covering less than every surface atom on said surface by irradiating the surface and the pattern of the adsorbed molecules with effective excitation energy to form a chemical bond between at least one constituent of the adsorbed molecules and the reactive solid locally to the sites where the adsorbed molecules are adsorbed on said surface, wherein said blocking agent does not imprint on said surface under irradiation.
