摘要：

Molecular alignments of poly(3-alkylthiophene)s deposited on the Au(111) facet are studied by scanning tunneling microscopy (STM). In regioregular poly(3-hexylthiophene) and poly(3-dodecylthiophene), the individual polymer is clearly imaged as a silkworm. On the other band, regiorandom poly(3-octadecylthiophene) does not show any distinguishable image of the individual polymer. The molecular shapes and the preparation method of the structurally aligned regioregular poly(3-alkylthiophene)s are described.
