摘要:
The formation of several molecular 2D tilings with long-range periodicity, including the Kagome network, distorted Kagome network, and snub trihexagonal tiling from the adsorption and assembly of thiacalix[4]arene tetrasulfonate (TCAS) at the 0.1 M HClO(4)/Au(111) interface has been investigated by electrochemical scanning tunneling microscopy (STM). The internal structures of the tilings have been disclosed by high-resolution STM images. The basic structural motifs, namely, the tiles of these tilings are similar, including triangular units and hexagonal units. Due to the different arrangement of the molecules within the triangular units, tiles with different configurations are formed, which further result in the polymorphism of the 2D tiling. This result is of significance for understanding the formation of 2D tiling as well as the design and construction of molecular self-assembled nanostructures.
