摘　　要：二维金属-有机框架纳米片是一类新兴的二维材料,其与块体材料相比具有更多可暴露的活性位点、快速的质子或电子传递等优点。制备易剥离的二维金属-有机框架纳米片的前驱体,即二维金属‐有机框架晶态材料是当前的一大挑战。以廉价且毒性较小的乙醇为反应介质、均苯三甲酸和N-基咪唑为共同配体,通过简单的一锅法制备了结构新颖的镍基二维金属-有机框架晶态材料Ni(C_(9)H_(3)O_(6))(C_(4)H_(6)N_(2))_(2)·0.6(C_(2)H_(5)OH)(1)和Ni_(3)(C_(9)H_(3)O_(6))_(3)(C_(5)H_(8)N_(2))_(6)·3.25(C_(2)H_(5)OH)(2),并对其进行了相关表征和剥离。实验中采用的反应介质乙醇毒性小、价格低廉、对环境污染性小且可循环利用,符合绿色化学的发展要求。该制备方法可为设计合成易剥离二维金属‐有机框架晶态材料提供借鉴。The two-dimensional metal-organic framework nanosheets represent a novel class of two-dimensional materials,featuring a more exposed active site,rapid proton or electron transfer,and other advantages than bulk materials.It is a major challenge to prepare two-dimensional metal-organic framework crystalline materials that are easy to peel off into two-dimensional metal-organic nanosheets at present.In this paper,two novel nickel based two-dimensional metal organic framework crystalline materials Ni(C_(9)H_(3)O_(6))(C_(4)H_(6)N_(2))_(2)·0.6(C_(2)H_(5)OH)(1)and Ni_(3)(C_(9)H_(3)O_(6))_(3)(C_(5)H_(8)N_(2))_(6)·3.25(C_(2)H_(5)OH)(2),were prepared by a simple one-pot method using cheap and less toxic ethanol as the reaction medium,trimesic acid and N-imidazole as common ligands,and characterized and exfoliated.The reaction medium used in the experiment,ethanol,is less toxic,cheap,less polluting to the environment,and can be recycled,which meets the requirements of green chemistry.This shed light on the design and synthesis of crystalline peelable two-dimensional metal-organic framework crystal materials.
