配位聚合物材料中的稳定自由基许颜清,李雨浓(北京理工大学化学与化工学院原子分子簇科学教育部重点实验室,北京100081)摘要:有机小分子自由基作为新型功能材料可能的构筑基元,与配位聚合物结合可以制备多种具有特殊功能的晶态材料.利用配位聚合物的理性设计和构筑来调控自由基的活性及性质,有着重要的理论意义和应用价值.文章首先介绍了多种在配位聚合物中能稳定存在的具有长寿命的自由基物种,包括紫精及类紫精衍生物、芳香酰亚胺类衍生物、氮氧类小分子自由基等.这些自由基物种以配位聚合物主链骨架、配体侧基或客体的形式稳定在配位聚合物基质中,然后重点讨论了它们在配位聚合物中稳定存在的可能原因,并简要介绍了其在智能窗口、传感器、光热治疗和催化等方面的潜在应用.最后总结了目前该领域发展的难点和不足,并提出未来的研究方向.关键词:稳定自由基;无机-有机杂化材料;配位聚合物;长寿命中图分类号:O626.32+1;TB381文献标志码:A文章编号:1001-0645(2023)03-0320-09DOI:10.15918/j.tbit1001-0645.2022.057StableRadicalsinCoordinationPolymerMaterialsXUYanqing,LIYunong(KeyLaboratoryofClusterScience,MinistryofEducationofChina,SchoolofChemistryandChemicalEngineering,BeijingInstituteofTechnology,Beijing100081,China)Abstract:Asapossiblebuildingblockofnewfunctionalmaterials,organicsmallmoleculeradicalscanbecom-binedwithcoordinationpolymerstoprepareavarietyofcrystallinematerialswithspecialfunctions.Toregulatetheactivityandpropertiesofradicalsinthecoordinationpolymersisoftheoreticalsignificanceandapplicationvalue.Inthispaper,avarietyoflong-livedradicalspeciesexistedstablyincoordinationpolymerswereintro-ducedfirstly,includingviologenderivatives,aromaticimidederivatives,nitrogenoxygensmallmoleculeradic-alsandsoon.Existingasmainskeleton,sidegrouporguestinthecoordinationpolymermatrix,theseradicalspecieswereanalyzedforthepossiblestabilityreasonsincoordinationpolymers.Andthen,theirpotentialap-plicationsinsmartwindows,sensors,photothermaltherapyandcatalysiswerebrieflyintroduced.Finally,thechallengesandshortcomingsinthisfieldweresummarizedforfutureresearch.Keywords:stableradicals;inorganic-organichybridmaterial;coordinationpoly...
