| We attempt to assemble surface mounted molecular rotors through a shaft-fan design. In a host alkanethiol self-assembled monolayer matrix, a shaft, a pyridine terminated oligo phenylene ethylene thiol is inserted. The fan of the rotor assembly, a metal porphyrin, is attached to the shaft via axial ligation with the pyridine terminal. These supramolecular structures are characterized by scanning tunneling microscopy (STM). We perform a systematic investigation on parameters such as the chain length of the alkanethiol matrix and the meter center of the porphyrins. We will discuss the STM contrast mechanism of these structures. |
