在高定向热解石墨(HOPG)表面上生长少量乙醇分子,在超低温(78K)高真空条件下通过STM针尖进行扫描,在扫描过程中施加4~5V的脉冲电压,乙醇分子或乙醇分子团簇就会带上负电,且能吸引周围的乙醇分子团簇或者乙醇分子链,如果受到吸引的团簇或分子链正好受到一定的扰动,那么该团簇或分子链就会围绕带电团簇转动或摆动,从而构成了靠静电力连接而成的超分子转子和马达.与以往液体中的超分子转子和马达,或者固体表面的单分子转子和马达不一样,这是一种置于固体表面的超分子转子和马达,且在隧穿电子的驱动下维持转动或摆动.
A small amount of ethanol molecules are grown on the surface of highly oriented pyrolytic graphite (HOPG), scanned by STM tip under the condition of ultra-low temperature (78K) high vacuum, pulse voltage of 4 ~ 5V is applied during scanning, ethanol molecules or ethanol molecular clusters It will bring negative electricity, and can attract the surrounding ethanol molecular or ethanol molecular chain, if the attracting cluster or molecular chain is subject to a certain disturbance, then the cluster or molecular chain will be around the charged cluster rotation or Swing to form the electrostatically connected supramolecular rotor and motor.And in the past the liquid supramolecular rotor and motor, or solid surface of the single molecule rotor and motor, which is a solid surface Supramolecular rotor and motor, and maintained by the tunneling electron driven rotation or swing.
