利用扫描隧道显微镜(STM)在液氮(LN2)温度下研究了半金属Bi(111)表面非手性CuPc分子的偏心轴分子转子和手性特征。每个CuPc分子转子的旋转轴位于酞菁基团的末端。随着分子覆盖率的增加,CuPc分子自组装成各种纳米簇,最终进入二维(2D)结构域,其中每个CuPc分子表现出明显的手性特征。CuPc分子的这种手性特征可归因于CuPc与Bi(111)底物之间的不对称电荷转移和分子间的范德华相互作用的综合作用。
Molecular rotors with an off-center axis and the chiral feature of achiral CuPc molecules on a semi-metallic Bi(111) surface have been investigated by means of a scanning tunneling microscopy (STM) at liquid nitrogen (LN2) temperature. The rotation axis of each CuPc molecular rotor is located at the end of a phthalocyanine group. As molecular coverage increases, the CuPc molecules are self-assembled into various nanoclusters and finally into two-dimensional (2D) domains, in which each CuPc molecule exhibits an apparent chiral feature. Such chiral features of the CuPc molecules can be attributed to the combined effect of asymmetric charge transfer between the CuPc and Bi(111) substrate, and the intermolecular van der Waals interactions.
