  "abstract": "亚胺类共价有机框架材料作为色谱柱分离固定相和样品预处理材料备受关注，但其形貌和形态调控仍面临挑战，严重限制了该类材料在分离分析领域的实际应用。近期研究发现，醛-胺聚合反应可以在低温冷冻条件下进行，且以1，4-二氧六环为溶剂冷冻形成的松针状晶体可构筑微米级的定向通孔；然而该模板的规整性有待提升。在此基础上，本研究提出以二甲基亚砜为醛-胺聚合反应体系的新型冷冻模板剂，利用其在低温下形成的针状晶体构筑更为规整的定向通孔结构，进而发展了一种基于醛-胺冷冻聚合反应制备亚胺类共价有机框架整体材料的新方法。首先在室温下配制单体质量分数为5%的均相预聚溶液，然后在液氮条件下使二甲基亚砜溶剂定向冷冻形成晶体模板；多元醛单体与多元胺单体聚集在晶体模板之间的缝隙中；将体系转移至-18 ℃进行聚合反应，形成无定形聚合物；最后通过晶化处理，该聚合物转化为共价有机框架整体材料。扫描电子显微镜图、粉末X射线衍射谱图和氮气物理吸附数据表明，该晶态框架整体材料具有微米级的定向通孔和纳米级的有序孔道；相比于1，4-二氧六环晶体模板所制备的整体材料，二甲基亚砜晶体模板诱导构筑的定向通孔结构更规整，通孔内壁光滑。进一步采用不同的醛-胺聚合反应体系，验证了“先冷冻成型，再高温晶化”的两步法成型策略制备共价有机框架整体材料的普适性，为推动该类材料在分离分析领域中的应用提供了有益借鉴。",
