【摘要】：金屬有機(jī)框架由金屬離子/集簇和有機(jī)配體構(gòu)成,由于其多孔性、大的表面積和結(jié)構(gòu)的可調(diào)等特性受到了科學(xué)家的廣泛關(guān)注。另一方面金屬有機(jī)框架結(jié)構(gòu)的特點(diǎn)也決定了它在氣體存儲(chǔ)/吸附、催化、磁性、藥物傳遞和傳感等方面的應(yīng)用。此外,熒光性的金屬有機(jī)框架在發(fā)光檢測(cè)/感應(yīng)和光催化方面也受到了科學(xué)家的青睞。四苯乙烯由四個(gè)苯環(huán)和一個(gè)乙烯鍵組成,在固態(tài)時(shí)具有良好的熒光性能常作為一種很好的聚集誘導(dǎo)發(fā)光(AIE)材料。因此,我們基于四苯乙烯單元引入咪唑基團(tuán)合成了剛性的四齒咪唑類有機(jī)配體四(4-咪唑基苯基)乙烯(TIPE)(L)并通過水熱法和后合成法合成了五個(gè)新穎的金屬有機(jī)框架1-5{[Cd_4(L)_2(OBBA)_4]·8H_2O}n(1)、{[Co_4(L)_2(BPDC)_4]·5MeCN·16H_2O}n(2)、{[Cu_4(L)3·5Cl}n(3)、{[Cd_4(L)_2]·2H_2O}n(4)和{[Co_4(L)_2(BPDC)_4]·2H_2O}n(5),利用PXRD、紅外光譜、X射線單晶衍射、元素分析等手段對(duì)其結(jié)構(gòu)進(jìn)行表征。另外,我們還進(jìn)行了氣體吸附、熒光感應(yīng)及催化性能的測(cè)試探索其潛在的應(yīng)用價(jià)值。結(jié)果顯示配合物1是一個(gè)三維四重穿插4-c afw網(wǎng)狀結(jié)構(gòu),它的拓?fù)浞?hào)為{{3.75}{3.7.7.7.7(2).7(2)}。在配合物2中鈷離子作為五鏈接節(jié)點(diǎn)而有機(jī)配體作為四鏈接節(jié)點(diǎn)整個(gè)結(jié)構(gòu)是一個(gè)少見的三維和三維相互穿插的四重穿插4,4-c 4T67網(wǎng)狀結(jié)構(gòu),用拓?fù)浞?hào)表示為{{4.64.8}2{42.62.82}。配合物3擁有罕見的[Cu_4Cl]~(3+)二級(jí)結(jié)構(gòu)單元,有機(jī)配體鏈接二級(jí)結(jié)構(gòu)單元整個(gè)結(jié)構(gòu)形成一個(gè)三維穿插的sqc6網(wǎng)狀結(jié)構(gòu)它的拓?fù)浞?hào)為{66}{6(2).6(2).6(2).6(2).6(2).6(2)}。配合物4是蝴蝶結(jié)型的鏈狀結(jié)構(gòu),鏈與鏈之間延伸形成一個(gè)二維結(jié)構(gòu)。配合物5是一個(gè)三維穿插結(jié)構(gòu),整個(gè)結(jié)構(gòu)中包含了兩種不同大小的通道,它們的尺寸大小分別為23.2602(13)×15.974(12)?2和24.6324(15)×14.5478(12)?2。熱穩(wěn)定性能分析顯示配合物1-4具有良好的熱穩(wěn)定性其分解溫度都在300℃以上。固體熒光測(cè)試證明配合物1、3和4有良好的熒光性能,配合物1更是對(duì)硝基爆炸物及甲基苯丙胺有良好的感應(yīng)效果。另外配合物4對(duì)1,3-偶極環(huán)化反應(yīng)具有良好的催化效果,當(dāng)反應(yīng)時(shí)間為3 h反應(yīng)溫度為60℃時(shí)產(chǎn)率可以達(dá)到90%以上。卟啉及金屬卟啉衍生物具有獨(dú)特的物理、化學(xué)、電學(xué)性能以及在能量和電子轉(zhuǎn)移、捕光、催化方面的特性,通過卟啉來構(gòu)建功能性的金屬有機(jī)框架受到了科研工作者的關(guān)注�；诖宋覀兒铣闪�5,10,15,20-四-(1,3-咪唑基)卟啉配體并在水熱條件下得到了金屬有機(jī)框架[Cd_3L_3Cl_3O_2]·solvent(6),X射線單晶衍射數(shù)據(jù)顯示其結(jié)構(gòu)為三斜p_1空間群。
[Abstract]:Metal organic frameworks are made up of metal ions / clusters and organic ligands. Due to their porous properties, large surface area and the adjustable structure, the characteristics of metal organic frame structure also determine its application in gas storage / adsorption, catalysis, magnetism, drug delivery and sensing. In addition, the fluorescent metallic organic frameworks are also favored by scientists in the field of luminescence detection / induction and photocatalysis. Four styrene is composed of four benzene rings and one ethylene bond, with good fluorescence properties in solid state as a good aggregation induced luminescent (AIE) material. Therefore, we introduce imidazole based on the four styrene unit. The group synthesized a rigid four diazolidic ligand four (4- imidazolyl phenyl) ethylene (TIPE) (L) and synthesized five novel metal organic frameworks 1-5{[Cd_4 (L) _2 (OBBA) _4]. 8H_2O}n (1), {[Co_4 (L) _2 (2), 3. (BPDC) _4]. 2H_2O}n (5), using PXRD, infrared spectrum, X ray single crystal diffraction, element analysis and other means to characterize its structure. In addition, we have also carried out gas adsorption, fluorescence induction and catalytic performance testing to explore its potential application value. Results show that complex 1 is a three-dimensional and four weight interspersed 4-C AFW network structure, its topology The symbol is {{3.75}{3.7.7.7.7 (2).7 (2)). In the complex 2 cobalt ion as the five link node and the organic ligand as the four link node the whole structure is a rare three-dimensional and three-dimensional interspersed four heavy 4,4-c 4T67 network structure, with the topology symbol expressed as the {{4.64.8}2{42.62.82}. complex 3 with a rare [Cu_4Cl]~ (3+) two. The structure unit, organic ligand links the two stage structure unit to form a three-dimensional and interspersed sqc6 network structure. Its topology symbol is {66}{6 (2).6 (2).6 (2).6 (2).6 (2).6 (2)). The complex 4 is a bow type chain structure, and the chain extends between the chain and the chain to form a two-dimensional structure. The complex 5 is a three-dimensional interspersed structure, the whole knot The structure contains two different sizes of channels, their size and size are 23.2602 (13) * 15.974 (12), 2 and 24.6324 (15) x 14.5478 (12)? 2., thermal stability analysis shows that the complex 1-4 has good thermal stability and its decomposition temperature is above 300. The solid fluorescence test proves that the complexes 1,3 and 4 have good fluorescence properties, fit together. The substance 1 has a good induction effect on nitro explosives and methamphetamine. In addition, the complex 4 has good catalytic effect on the 1,3- dipole cyclization reaction. When the reaction time is 3 h, the yield can reach more than 90%. Porphyrin and metalloporphyrin derivatives have unique physical, chemical, electrical properties and energy. The properties of electron transfer, light capture and catalysis have attracted the attention of researchers. Based on this, we synthesized the 5,10,15,20- four - (1,3- imidazolyl) porphyrin ligand and obtained the metal organic framework [Cd_3L_3Cl_3O_2]. Solvent (6), X ray single crystal diffraction data under the hydrothermal condition. It is shown that its structure is three oblique p_1 space group.
