【《金属有机凝胶的分类分析》3000字】

金属有机凝胶的分类分析MOGs是通过金属离子和有机桥连剂通过配位相互作用形成具有无限延伸结构特性的配位聚合物，它与金属有机骨架（Metalorganicframeworks，MOFs）的区别在于他们的形成机制和物理形态不同。MOFs的形成包括成核和生长两个过程形成的晶状粉末，可通过经典的晶体理论解释；而MOGs是基于胶体化学理论形成的具有粘弹性的类似固体材料。有机配体在MOGs的形成过程中起着至关重要的桥联作用。研究发现：含有长链烷基、羧酸基团、酰胺基团以及吡啶类官能团的有机分子桥连剂作为金属离子的配体更容易形成凝胶体系。金属离子作为MOGs的重要组成部分影响其性能。因此本文根据金属元素的种类不同，以常见的贵金属、铜、铁、铝和稀土元素金属离子对MOGs进行分类介绍。基于银离子(Ag+)的MOGs显示出光催化ADDINEN.CITE<EndNote><Cite><RecNum>575</RecNum><DisplayText><styleface="superscript">[25,35]</style></DisplayText><record><rec-number>575</rec-number><foreign-keys><keyapp="EN"db-id="fr5x0trs4s2v5rep0se5v52vv9zr0t9pdpr9"timestamp="1611063950">575</key><keyapp="ENWeb"db-id="">0</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors></contributors><titles><title><d0dt02919j.pdf></title></titles><dates></dates><urls></urls></record></Cite><Cite><Author>Xiao</Author><Year>2020</Year><RecNum>540</RecNum><record><rec-number>540</rec-number><foreign-keys><keyapp="EN"db-id="fr5x0trs4s2v5rep0se5v52vv9zr0t9pdpr9"timestamp="1611060103">540</key><keyapp="ENWeb"db-id="">0</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>Xiao,SiYu</author><author>Li,Yang</author><author>Zhen,ShuJun</author><author>Huang,ChengZhi</author><author>Li,YuanFang</author></authors></contributors><titles><title>Efficientperoxydisulfateelectrochemiluminescencesystembasedthenovelsilvermetal-organicgelasaneffectiveenhancer</title><secondary-title>ElectrochimicaActa</secondary-title></titles><periodical><full-title>ElectrochimicaActa</full-title><abbr-1>Electrochim.Acta</abbr-1><abbr-2>ElectrochimActa</abbr-2></periodical><volume>357</volume><section>136842</section><dates><year>2020</year></dates><isbn>00134686</isbn><urls></urls><electronic-resource-num>10.1016/j.electacta.2020.136842</electronic-resource-num></record></Cite></EndNote>[25,35]、表面增强拉曼散射(SERS)、ADDINEN.CITEADDINEN.CITE.DATA[36,37]，多重刺激响应性ADDINEN.CITEADDINEN.CITE.DATA[38,39]、聚集诱导发射和荧光-磷光转换ADDINEN.CITEADDINEN.CITE.DATA[40,41]等有趣的性质。MandalADDINEN.CITE<EndNote><Cite><RecNum>575</RecNum><DisplayText><styleface="superscript">[25]</style></DisplayText><record><rec-number>575</rec-number><foreign-keys><keyapp="EN"db-id="fr5x0trs4s2v5rep0se5v52vv9zr0t9pdpr9"timestamp="1611063950">575</key><keyapp="ENWeb"db-id="">0</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors></contributors><titles><title><d0dt02919j.pdf></title></titles><dates></dates><urls></urls></record></Cite></EndNote>[25]等人利用亚苯基-1,3-二取代双烯烃酰胺分子（3PMA）和银盐制备了Ag-MOGs，所制备的干Ag-MOGs在光照时表现出优异的光催化催化能力，并探索了在光催化[2+2]聚合反应前后Ag-MOGs的固态发光行为和对染料的选择性吸附行为。李ADDINEN.CITE<EndNote><Cite><Author>Li</Author><Year>2019</Year><RecNum>549</RecNum><DisplayText><styleface="superscript">[36]</style></DisplayText><record><rec-number>549</rec-number><foreign-keys><keyapp="EN"db-id="fr5x0trs4s2v5rep0se5v52vv9zr0t9pdpr9"timestamp="1611060775">549</key><keyapp="ENWeb"db-id="">0</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>Li,Yang</author><author>Guo,MaoXia</author><author>He,Li</author><author>Huang,ChengZhi</author><author>Li,YuanFang</author></authors></contributors><titles><title>GreenOne-PotSynthesisofSilverNanoparticles/Metal–OrganicGelsHybridandItsPromisingSERSApplication</title><secondary-title>ACSSustainableChemistry&Engineering</secondary-title></titles><periodical><full-title>ACSSustainableChemistry&Engineering</full-title></periodical><pages>5292-5299</pages><volume>7</volume><number>5</number><section>5292</section><dates><year>2019</year></dates><isbn>2168-0485 2168-0485</isbn><urls></urls><electronic-resource-num>10.1021/acssuschemeng.8b06305</electronic-resource-num></record></Cite></EndNote>[36]等人通过简单地混合4-(2,2':6',2''-叔吡啶)-4'-苯甲酸（Hcptpy）和银离子（Ag+）制备出AgNPs/MOGs杂化物。在该反应过程中不需要额外加入还原剂，且由于Hcptpy的拉曼标记源性和AgNPs的局部表面等离子体共振特性，所制备的AgNPs/MOGs杂化物显示出色的拉曼信号，并可作为一种出色的表面增强拉曼散射（SurfaceEnhancedRamanScattering,SERS）平台用于高锰酸盐高灵敏度的检测。值得注意的是，Hcptpy在杂化物的合成中起着螯合和还原的双重作用，既可作为配位剂与Ag+配位形成MOGs，也可作为还原剂将Ag+原位还原形成AgNPs。以铜离子(Cu2+)合成的MOGs可作用纳米酶（过氧化物酶）ADDINEN.CITEADDINEN.CITE.DATA[42-45]，光催化剂ADDINEN.CITE<EndNote><Cite><Author>Oldenhuis</Author><Year>2020</Year><RecNum>556</RecNum><DisplayText><styleface="superscript">[46]</style></DisplayText><record><rec-number>556</rec-number><foreign-keys><keyapp="EN"db-id="fr5x0trs4s2v5rep0se5v52vv9zr0t9pdpr9"timestamp="1611061148">556</key><keyapp="ENWeb"db-id="">0</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>Oldenhuis,N.J.</author><author>Qin,K.P.</author><author>Wang,S.</author><author>Ye,H.Z.</author><author>Alt,E.A.</author><author>Willard,A.P.</author><author>VanVoorhis,T.</author><author>Craig,S.L.</author><author>Johnson,J.A.</author></authors></contributors><auth-address>DepartmentofChemistry,MassachusettsInstituteofTechnology,Cambridge,MA,02139,USA.
