本文系统地研究了1，3，5-三（4-羧基苯基）苯（TCPB）和4，4“-二氨基对三联苯（DATP）在银表面的共组装行为。由于羧酸的热不稳定性，共组装结构在Ag（111）上表现出温度依赖性的演变。TCPB的去质子化反应的水平由特征自组装足迹澄清。借助这些足迹，我们能够识别TCPB和DATP实体在每个阶段的复杂共组装的结构。最后，通过密度泛函理论计算进一步验证了上述结论.
In this work, we systematically studied the co-assembly behavior of 1,3,5-tris(4-carboxyphenyObenzene (TCPB) and 4,4 ''-diamino-p-terphenyl (DATP) on a silver surface. Due to the thermal instability of carboxylic acids, the co-assembled structure exhibits temperature-dependent evolutions on Ag(111). The level of the deprotonation reactions of TCPB are clarified by the characteristic self-assembled footprints. Aided by these footprints, we are able to identify the structures of the complex co-assembly of TCPB and DATP entities at each stage. Finally, the conclusions are further evidenced by density functional theory calculations.
