style=\"color:red\">有</span>热稳定性高、比表面积大以及稀土离子配位环境多样等优点,近年来受到国内外研究者关注和重视.后合成修饰<span style=\"color:red\">法</span>(PSM)是利用MOFs骨架中不饱和配位的金属离子或潜在的<span style=\"color:red\">有机</span>反应基团,通过配位键或共价键方式引入<span style=\"color:red\">有机</span>或无机分子,制备具<span style=\"color:red\">有</span>新功能的骨架材料.本文采用PSM策略,将三种不同的<span style=\"color:red\">有机</span>二<span style=\"color:red\">胺</span>后合成修饰到具<span style=\"color:red\">有</span>配位不饱和位点的稀土金属<span style=\"color:red\">有机</span>骨架[Er(btc)]的孔道中,得到三种固体碱催化剂：Er(btc)(ED)0.75(H2O)0.25(2), Er(btc)(PP)0.55(H2O)0.45(3)和Er(btc)(DABCO)0.15(H2O)0.85(4).其中, btc为1,3,5-均苯三甲酸, ED为乙二<span style=\"color:red\">胺</span>, PP为哌嗪, DABCO位为三乙烯二<span style=\"color:red\">胺</span>.单晶结构分析表明,在[Er(btc)(H2O)]·DMF0.7(1)中,铒离子与六个btc配体的六个羧酸氧原子和一个水分子配位,形成变形的五角双锥几何构型.每个btc配体连接六个铒离子构成具<span style=\"color:red\">有</span>一维开放孔道(0.7 nm′0.7 nm)的三维立体结构.重要的是,孔道中的配位水分子和游离DMF分子可通过真空加热除去而不影响其骨架结构(热稳定性达500 oC),这将<span style=\"color:red\">有</span>利于对其进行后合成修饰.热重分析(TGA)表明,催化剂2在25–300 oC失去孔道中配位的乙二<span style=\"color:red\">胺</span>和水分子；催化剂3在250 oC之前失去孔道中的哌嗪和水分子；催化剂4则在100 oC之前失去孔道中配位的三乙烯二<span style=\"color:red\">胺</span>和水分子.粉末X射线衍射(PXRD)结果显示,后合成修饰过程并没<span style=\"color:red\">有</span>改变催化剂骨架的稳定性,其稳定性在空气中超过30 d.氮气吸附实验表明, Ln-MOF 1的比表面积和孔体积分别为2000 m2/g和0.75 cm3/g,平均孔尺寸为0.65 nm,与晶体结构分析结果基本一致.相比之下,后合成修饰的催化剂2的比表面积明显降低,为650 m2/g,而催化剂3和4由于后修饰较大体积的二<span style=\"color:red\">胺</span>分子(哌嗪和三乙烯二<span style=\"color:red\">胺</span>),表现出可忽略的氮气吸附能力.上述结果表明,催化剂2具<span style=\"color:red\">有</span>较高的<span style=\"color:red\">有机</span><span style=\"color:red\">胺</span>负载量、较高的热稳定性和多孔性.采用苯甲醛和丙二腈的Knoevenagel缩合反应研究了三种固体碱的非均相催化能力.结果表明,在相同反应条件下,催化剂2具<span style=\"color:red\">有</span>很好的首次催化能力(99%),优于催化剂3(93%)和4(63%).并且,催化剂2循环使用三次后,催化能力几乎没<span style=\"color:red\">有</span>改变,而催化剂3和4的催化能力则逐渐降低,催化剂4在第三次使用时已无催化能力.滤出实验显示,催化剂2在反应过程中无活性物种离去进入液相体系中,即无乙二<span style=\"color:red\">胺</span>分子从催化剂骨架孔道中离去,证明其为非均相催化本质.而催化剂3和4则在反应过程中<span style=\"color:red\">有</span>二<span style=\"color:red\">胺</span>分子离去,进入反应液相中,从而导致其循环使用催化能力降低.催化剂2的底物择形催化反应结果显示,先是丙二腈分子进入催化剂孔道中,形成碳负离子,然后亲核进攻醛分子生成产物.因此,体积较大的腈衍生物因不能进入孔道而不能发生反应,而体积较大的醛分子则不受影响,能顺利地发生反应.","authors":[{"authorName":"任颜卫","id":"934e17f2-1769-40e4-b283-62f00bb338b6","originalAuthorName":"任颜卫"},{"authorName":"陆家贤","id":"370d967e-35fc-4e07-861e-f7c58fdae83d","originalAuthorName":"陆家贤"},{"authorName":"江鸥","id":"1af2d9ab-9b2f-433d-b6db-497508cb0bad","originalAuthorName":"江鸥"},{"authorName":"程晓飞","id":"3d70f9c7-850d-447b-a1f7-6ffac37ee947","originalAuthorName":"程晓飞"},{"authorName":"陈俊","id":"2cfbc21a-84fc-4f27-af75-3ce77e2b1a0e","originalAuthorName":"陈俊"}],"doi":"10.1016/S1872-2067(15)60945-7","fpage":"1949","id":"46adf82d-2675-4471-bd71-95b3a8708c57","issue":"11","journal":{"abbrevTitle":"CHXB","coverImgSrc":"journal/img/cover/CHXB.jpg","id":"18","issnPpub":"0253-9837","publisherId":"CHXB","title":"催化学报
