Spontaneously ordered monolayers on graphite are formed by the new synthezised class of steroid‐bridged oligothiophenes 1 a–c ; in STM images these appear in all cases as bright (thiophene) and dark (steroid) areas due to different energy gaps of the subunits. The formyl groups influence the structure patterns.
