The invention sets forth a method to connect diamond powders with other diamond powders or to connect diamond powders with substrates by cycloaddition reactions. The diamond powders are pretreated to desorb non-carbon surface atoms. The cycloaddition reactions are between clean diamond surfaces and C-C double bonds in the cross-linking molecules, which are either conjugated or not. The reactions are performed at temperatures <200 Celsius degree. The cross-linking molecules are covalently bonded to diamond powders through C-C single bonds. The method produces diamond structures with big sizes. The diamond structures produced by the method can be chemically stable. The diamond structures produced by connecting diamond powders are porous.
