Novel growth method of two-dimensional organic polymer through two-dimensional crystal surface catalysis

Abstract

The invention provides a novel growth method of a two-dimensional organic polymer through two-dimensional crystal surface catalysis. A solid-liquid interface rapid preparation method is adopted to directly prepare a two-dimensional cuprous chloride nano-crystal material which has template and catalysis effects on a copper foil substrate; 1,3,5-tribromobenzene and p-phenylenediamine are used as monomer molecules; polymerization reaction is directly carried out on the surface of a two-dimensional cuprous chloride nano-crystal which is used as a catalyst, so as to obtain the two-dimensional organic polymer. According to the method disclosed by the invention, the two-dimensional organic polymer is prepared from specific monomers by utilizing surface-catalyzed reaction and two-dimensional organic polymerization reaction types are widened.

technical field

[0001] The invention relates to the field of preparation of two-dimensional organic polymer materials, in particular to a method for catalyzing the growth of two-dimensional organic polymers on a two-dimensional crystal surface. Background technique

[0002] Two-dimensional organic polymers refer to a network structure that is covalently linked by organic monomers and has periodicity in two orthogonal directions. Due to their special structures, two-dimensional organic polymers have broad application prospects in gas adsorption, material sieving, and devices. For the polymerization of monomer molecules in the solution, the monomers currently involved mainly include organoboric acid, organoboric acid / catechol, aniline / benzaldehyde and benzocyanide, etc., and the reactions involved at the same time are boric acid trimerization condensation and boron ester condensation , Aldehyde-amine condensation and cyanotrimerization reaction. In 2005, and Yaghi et al. r...
