报告简介：
Combingscanning probe microscopy with density functional theory, molecular mechanicsand Monte Carlo simulation, we have systematically investigated the design andconstruction of two-dimensional covalent architectures via dynamic covalentbonds, and investigated the reaction/assembling mechanism and properties ofthese novel two-dimensional materials. We demonstrated the key role played bythe adsorption and assembling of reaction precursors in the surface confineddynamic covalent chemistry, both in controlling the reaction and productselection. We have also proved the applicability of theconcentration-in-control strategy, which was first reported by us in thesupramolecular assembling studies, in the surface confined synthesis of poroustwo-dimensional polymers. We have systematically investigated the determiningfactors in the surface confined dynamic covalent reaction, and clearlydemonstrated the significant role played by the preferential adsorption,concentration and molar ratio of reaction precursors. Appling theconcentration-in-control strategy we have developed an easy and low costprocedure for the room temperature preparation of conjugated two-dimensionalpolymers with very good regularity and continuity, both on the surface ofgraphite and graphene. By introducing chemical and photo active groups we havealso realized the on-surface synthesis of functional 2D polymers, and exploredtheir application in electro-energy storage and photodetection. We have alsoconducted systematic investigations on the mechanism of on-surfacepolymerization and physical properties of two-dimensional polymers by combiningSPM with DFT and Monte Carlo simulation.
