In this work, the two-dimensional self-assembly and co-assembly behaviors of two tetracarboxylic acid derivatives (H₄BDETP and H₄BTB) were investigated by scanning tunneling microscopy (STM). H₄BDETP molecules self-assembled into linear nanostructures, and H₄BTB molecules formed lamellar and tetragonal nanostructures. The formation of a H₄BDETP/H₄BTB co-assembly nanostructure was closely related to the deposition sequence of H₄BDETP and H₄BTB on highly oriented pyrolytic graphite (HOPG). The introduction of H₄BTB into the self-assembly system of H₄BDETP resulted in the emergence of the H₄BDETP/H₄BTB nanostructure, while the addition of H₄BDETP had no effect on the self-assembly system of H₄BTB and a H₄BDETP/H₄BTB co-assembly nanostructure was not obtained.

STM研究两种四羧酸衍生物的二维自组装和共组装

在这项工作中，通过扫描隧道显微镜（STM）研究了两种四羧酸衍生物（H ₄ BDETP和H ₄ BTB）的二维自组装和共组装行为。H ₄ BDETP分子自组装成线性纳米结构，H ₄ BTB分子形成层状和四方纳米结构。_{H 4} BDETP/H ₄ BTB共组装纳米结构的形成与H ₄ BDETP和H ₄ BTB在高取向热解石墨(HOPG)上的沉积顺序密切相关。_{在H 4} BDETP自组装体系中引入H _{4 BTB导致了H}₄ BDETP/H ₄ BTB纳米结构的出现，而H ₄ BDETP的添加对H ₄ BDETP自组装体系没有影响。未获得BTB和H ₄ BDETP/H _{4 BTB共组装纳米结构。}
