在过去的几年里，二维(2D)纳米孔网络作为模板引起了人们的极大兴趣，用于精确定位和限制客体构建块，如固体表面上的功能分子或团簇。在本论文中，我们在石墨表面构建了一系列具有三重对称性的双组分分子网络，使用的是吐克逊酮衍生物和带有羧酸端烷基链的三偏位酸同系物。氢键伙伴识别诱导的烷基链的2D结晶使柔性烷基链在网络中充当刚性间隔体，以每步一个碳原子的精度连续调节孔径。双组分网络被发现调节和调节客体分子的分布和聚集，如CoR和CuPc。该方法为固体表面分子纳米结构的设计和制备提供了一条新的途径。
Over the past few years, two-dimensional (2D) nanoporous networks have attracted great interest as templates for the precise localization and confinement of guest building blocks, such as functional molecules or clusters on the solid surfaces. Herein, a series of two-component molecular networks with a 3-fold symmetry are constructed on graphite using a truxenone derivative and trimesic acid homologues with carboxylic-acid-terminated alkyl chains. The hydrogen-bonding partner-recognition-induced 2D crystallization of alkyl chains makes the flexible alkyl chains act as rigid spacers in the networks to continuously tune the pore size with an accuracy of one carbon atom per step. The two-component networks were found to accommodate and regulate the distribution and aggregation of guest molecules, such as COR and CuPc. This procedure provides a new pathway for the design and fabrication of molecular nanostructures on solid surfaces.
