摘      要：Patterned covalent functionalization of graphitic surfaces(GSs)is of interest in the development of devices and nanocomposite *** contrast to the strategies using external templates or control for realizing patterned covalent functionalization of GSs,here,we present a self-templated strategy by exploiting the synergistic effects of chemical and physical functionalization of ***,a diazonium salt is reduced by potassium iodide(KI)in dimethyl sulfoxide while the solution is in contact with a GS,resulting in its spatially heterogeneous,that is,chemical and physical,*** heterogeneous functionalization leads to a quasiperiodic pattern of striped corrals with three equivalent orientations in the covalent *** formation of the striped corrals is ascribed to physisorbed domains formed by self-assembled N_(2),which is produced in situ during the reduction of the diazonium salt,preventing the covalent functionalization.
