The formation of nanostructures with concomitant patterns and functions is of utmost importance in the field of surface molecular engineering and nanotechnology. With the carefully designed peripheral functional groups to facility intermolecular interactions, the sophisticated nanoporous structures with ordered pattern on solid supports can be tailored, which could serve as template to regulate surface orientation and distribution of functional molecules and nano-objects. In this presentation, recent advances toward molecular engineering of molecular nanoporous networks with defined size and periodicity on solid supports will be discussed. We demonstrated that the complementary hydrogen bond partner recognition has been utilized to construct two-component nanoporous network with alkyl chains as spacers between network nodes.<br/>Beyond weak intermolecular interaction, the nanoporous networks interconnected through covalent bond have attracted great attention due to their graphene-like topology and the associated properties. the key challenge urgent to address for synthesis of high quality sCOFs is how to obtain desired topological structures with perfect structural uniformity. Recently, we have demonstrated that the high quality large scale sCOF synthesis can be achieved by tuning the thermodynamic equilibrium and growth kinetics. This presentation will focus on the synthetic methodology for the on-surface fabrication of high quality sCOF materials.
