Aliphatic tertiary amine functionalized chromium-based metal organic framework material and preparation method thereof

The invention belongs to the technical field of metal organic synthesis, and particularly relates to an aliphatic tertiary amine functionalized chromium-based metal organic framework material and a preparation method. The preparation method comprises the following steps: firstly, taking formyl pre-functionalized organic ligand and inorganic metal salt as raw materials, and preparing a formyl functionalized chromium-based metal organic framework material by adopting a solvothermal method; immersing a formyl functionalized material in a corresponding formamide organic compound, using formic acidas a reducing agent, and preparing the corresponding aliphatic tertiary amine functionalized metal organic framework material through reductive amination at enough temperature. The method provided bythe invention has excellent flexibility, and wider conditions and substrates can be selected when a tertiary amine structure is introduced. 本发明属于金属有机合成技术领域，具体涉及一种脂肪族叔胺功能化铬基金属有机框架材料和制备方法。本发明首先以甲酰基预功能化的有机配体和无机金属盐为原料，采用溶剂热方法制备出甲
