Abstract
The molecular alignment of an alkylthiophene, 3-n-octadecylthiophene, on highly oriented pyrolytic graphite has been studied by scanning tun neling microscopy (STM). Lateral stripes with a period of 0.42 nm and vertical stripes with one of 5.0 nm are observed and assigned to molec ular alignments of alkyl chains and thiophene rings connected by ''hea d to head'', respectively. An STM image of N-n-octadecylpyrrole is als o presented.
