摘要：

The growth of thiophene/phenylene cooligomers is investigated on the basal surface of muscovite mica. Both the phenyl end-capped 5,5'-di-4-biphenylyl-2,2'-bithiophene (PPTTPP) and the thienyl end-capped 4,4'-di-2,2'-bithienylbiphenyl (TTPPTT) co-oligomers form fiberlike nanostructures from molecules lying on the substrate surface after vacuum deposition. The fibers are oriented either in two distinct orientations or in a range of directions between two maximal orientations. On a microscopic level, PPTTPP growth is more similar to the growth of p-phenylene oligomers on muscovite, whereas TTPPTT is more similar to the growth of alpha-thiophene oligomers.
