NOVELTY - Preparing metal organicframework hole inner-layer graphite alkyne involves selecting growth substrate metal organicframework, choosing copper-containing metal organicframework with a pore size in the range of as the growth substrate, confining growth within metal organicframework pores of oligo-layer graphyne, dispersing the copper-containing metal organicframework material powder in acetone and mixing to obtain mixed solution A, which is protected by nitrogen, pre-dissolving hexaethynylbenzene in acetone, then slowly adding dropwise to mixed solution A under dark conditions, stirring the reaction, filtering, washing, centrifuging, and drying to obtain the metal organicframework oligolayer graphyne (Cu) composite material B. USE - Method for preparing metal organic framework hole inner-layer graphite alkyne used in conductive materials, photoelectric detection and catalytic materials (claimed). ADVANTAGE - The method limits the growth space of the graphite alkyne, so as to effectively inhibit the stack in the growth process of the graphite alkyne. DETAILED DESCRIPTION - Preparing metal organicframework hole inner-layer graphite alkyne involves selecting growth substrate metal organicframework, choosing copper-containing metal organicframework with a pore size in the range of as the growth substrate, confining growth within metal organicframework pores of oligo-layer graphyne, dispersing the copper-containing metal organicframework material powder in acetone and mixing to obtain mixed solution A, which is protected by nitrogen, pre-dissolving hexaethynylbenzene in acetone, then slowly adding dropwise to mixed solution A under dark conditions, stirring the reaction, filtering, washing, centrifuging, and drying to obtain the metal organicframework oligolayer graphyne (Cu) composite material B, where the mass ratio of the copper-containing metal organicframework material to hexaethynylbenzene is 10:0.2-2.5, dispersing the composite material B prepared in water to obtain solution C, then adding disodium edetate to solution C, and dissolving the material in a constant temperature water bath, subjecting to centrifugation and drying to obtain product.
