我们报道了CoPc-空位的高度有序排列和空位中的单分子转子。当CoPc分子低温沉积在Cd(0001)上时，CoPc单层中随机出现了三种类型的分子空位。样品在较高温度下退火后，空位自发分离，空位自组织排列。得到了高度有序的双分子空位和单分子空位阵列。特别是，在每个单分子空位中都有一个旋转的COPC分子，这构成了单分子转子的阵列。这些结果为大规模制造纳米机器提供了新的途径。
We report the highly ordered array of CoPc-vacancies and the single-molecule rotors inside the vacancies. When CoPc molecules are deposited on Cd(0001) at low-temperature, three types of molecular vacancies appeared randomly in the CoPc monolayer. Annealing the sample to higher temperature leads to the spontaneous phase separation and self-organized arrangement of the vacancies. Highly ordered arrays of two-molecule vacancies and single-molecule vacancies have been obtained. In particular, there is a rotating CoPc molecule inside each single-molecule vacancy, which constitutes the array of single-molecule rotors. These results provide a new routine to fabricate the nano-machines on a large scale.
