Characteristic Molecular Patterns Formed by N-Octadecylbenzamide and N-8-Quinolyloctadecanamide Selfassembled on a Graphite Surface

Self-assembled monolayers of N-octadecylbenzamide (ODB) and N-8-quinolyloctadecanamide (ODQ) have been observed on the solution-solid interface by scanning tunneling microscope (STM). ODB molecules form stripe shaped lamella structure whereas ODQ gave a mosaic pattern in which four molecular sets are interlocked alternately like jigsaw pieces.
