At the liquid/graphite interface triangular and rhombic phenylene-ethynylene macrocycles substituted by alkyl chains self-assemble to form porous two-dimensional (2D) molecular networks of honeycomb and Kagomé types, respectively, or close-packed non-porous structures via alkyl chain interdigitation as the directional intermolecular linkages. Factors that affect the formation of the 2D molecular networks, such as alkyl chain length, solvent, solute concentration, and co-adsorption of guest molecules, were elucidated through a systematic study. For the porous networks, various molecules and molecular clusters were adsorbed in the pores reflecting the size and shape complementarity, exploring a new field of 2D host-guest chemistry.
在液态/石墨界面处，三角形和菱形的苯乙炔大环通过烷基链自组装，分别形成蜂窝状和正三角形类型的多孔二维（2D）分子网络，或通过烷基链交错形成紧密堆积的无孔结构，作为定向的分子间连接。通过系统研究，阐明了影响 2D 分子网络形成的因素，如烷基链长度、溶剂、溶质浓度以及客体分子的共吸附。对于多孔网络，各种分子和分子簇被吸附在孔中，反映了大小和形状的互补性，为二维主客体化学开辟了一个新的领域。
