Oligo(N(6)-carbobenzyloxy-L-lysine) (OCBL) with n = 8 (n is the number-average degree of polymerization) was synthesized by the n-propylamine-catalyzed ring-opening polymerization of N(6)-carbobenzyloxy-L-lysine N-carboxylic anhydride, which was derived from N(6)-carbobenzyloxy-L-lysine. The formation of two-dimensionally well-ordered strip array monolayer films of the OBCL oligopeptide on graphite substrates was first succeeded by a conventional solution spin-coating process. The ordered strip array monolayer structure was characterized in detail by atomic force microscopy, and its assembly mechanism was examined.
