A stepwise ligand exchange strategy is utilized to prepare a series of isoreticular bio-MOF-100 analogs. Specifically, in situ ligand exchange with progressively longer dicarboxylate linkers is performed on single crystalline starting materials to synthesize products with progressively larger mesoporous cavities. The new members of this series of materials, bio-MOFs 101-103, each exhibit permanent mesoporosity and pore sizes ranging from ∼2.1-2.9 nm and surface areas ranging from 2704 to 4410 m2/g. The pore volume for bio-MOF 101 is 2.83 cc/g. Bio-MOF-102 and 103 have pore volumes of 4.36 and 4.13 cc/g, resp. Collectively, these data establish this unique family of MOFs as one of the most porous reported to date. The experimental process involved the reaction of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate(cas: 1312703-30-2).Recommanded Product: 1312703-30-2

On July 31, 2022, Li, Huai-Ming; Li, Guan-Dong; Li, Jun-Yu; Zhang, Teng published an article.SDS of cas: 1312703-30-2 The title of the article was An Iodine-Functionalized Metal-Organic framework for catalytic alkene bromination. And the article contained the following:

An iodine-functionalized metal-organic framework (MOF), UiO-68-I, was synthesized. UiO-68-I showed good catalytic activity for dibromination of alkenes and alkynes with a low catalyst loading of 1% and was able to be recycled and recovered efficiently. Mechanistic studies suggest that UiO-68-I may trigger the formation of mol. bromine through a radical intermediate and thus accelerate the reaction. The activity and stability of UiO-68-I outperforms most earlier reports on organoiodine catalysts, showing the great potential of iodine-functionalized MOFs as recyclable heterogeneous hypervalent iodine reagents or catalysts.

On August 3, 2020, Newar, Rajashree; Begum, Wahida; Antil, Neha; Shukla, Sakshi; Kumar, Ajay; Akhtar, Naved; Balendra; Manna, Kuntal published an article.Quality Control of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate The title of the article was Single-Site Cobalt-Catalyst Ligated with Pyridylimine-Functionalized Metal-Organic Frameworks for Arene and Benzylic Borylation. And the article contained the following:

A highly active single-site heterogeneous cobalt-catalyst is reported based on a porous and robust pyridylimine-functionalized metal-organic frameworks (pyrim-MOF) for chemoselective borylation of arene and benzylic C-H bonds. The pyrim-MOF having UiO-68 topol., constructed from zirconium-cluster secondary building units and pyridylimine-functionalized dicarboxylate bridging linkers, was metalated with CoCl2 followed by treatment of NaEt3BH to give the cobalt-functionalized MOF-catalyst (pyrim-MOF-Co). Pyrim-MOF-Co has a broad substrate scope, allowing the C-H borylation of halogen-, alkoxy-, alkyl-substituted arenes as well as heterocyclic ring systems using B2pin2 or HBpin (pin = pinacolate) as the borylating agent to afford the corresponding arene- or alkyl-boronate esters in good yields. Pyrim-MOF-Co gave a turnover number (TON) of up to 2500 and could be recycled and reused at least 9 times. Pyrim-MOF-Co was also significantly more robust and active than its homogeneous control, highlighting the beneficial effect of active-site isolation within the MOF framework that prevents intermol. decomposition The exptl. and computational studies suggested (pyrim•-)CoI(THF) as the active catalytic species within the MOF, which undergoes a mechanistic pathway of oxidative addition, turnover limiting σ-bond metathesis, followed by reductive elimination to afford the boronate ester. The pyridylimine-functionalized metal-organic framework (pyrim-MOF)-based single-site cobalt-catalyst is efficient for chemoselective borylation of arene and benzylic C-H bonds. The heterogeneous MOF-catalyst is significantly more robust and active than its homogeneous control, highlighting the beneficial effect of active-site isolation within the MOF framework that prevents intermol. decomposition The experimental process involved the reaction of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate(cas: 1312703-30-2).Quality Control of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate

On April 26, 2016, Kutzscher, Christel; Nickerl, Georg; Senkovska, Irena; Bon, Volodymyr; Kaskel, Stefan published an article.Synthetic Route of 1312703-30-2 The title of the article was Proline Functionalized UiO-67 and UiO-68 Type Metal-Organic Frameworks Showing Reversed Diastereoselectivity in Aldol Addition Reactions. And the article contained the following:

Functionalization of dicarboxylate linkers with proline was used to generate catalytically active metal-organic frameworks (MOFs) for diastereoselective aldol addition Due to high robustness and chem. stability, zirconium based MOFs, namely UiO-67 and UiO-68, were chosen as catalyst hosts. During the MOF synthesis, utilizing Boc protected proline functionalized linkers H2bpdc-NHProBoc and H2tpdc-NHProBoc, in situ deprotection of the Boc groups without racemization is achieved, enabling direct application of the enantiopure, homochiral MOFs in catalytic reaction, without further postsynthetic treatment. Solvent screening and kinetic studies as well as cycling tests were used to evaluate the conditions for diastereoselective aldol addition using a model reaction of 4-nitrobenzaldehyde and cyclohexanone. High yields (up to 97%) were achieved in reasonable reaction time using ethanol as solvent. In comparison to homocatalytic reactions catalyzed by L-proline and its derivatives, MOFs showed opposite diastereoselectivity attributed to the catalytic sites in confined pore space rendering this class of materials as promising catalysts for fine chems. production The experimental process involved the reaction of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate(cas: 1312703-30-2).Synthetic Route of 1312703-30-2

Zhang, Zhen-Yu; Wang, Qian; Hou, Ping-Ping; Shen, Zhihao; Fan, Xing-He published an article in 2015, the title of the article was Effects of rigid cores and flexible tails on the phase behaviors of polynorbornene-based mesogen-jacketed liquid crystalline polymers.Formula: C22H19NO4 And the article contains the following content:

A new series of mesogen-jacketed liquid crystalline polymers (MJLCPs) with a polynorbornene main chain and different side groups were prepared by ring-opening metathesis polymerization The liquid crystalline (LC) phase behaviors of these polymers were investigated by differential scanning calorimetry, polarized light microscopy, and wide-angle X-ray diffraction. Depending on the rigid side-chain core and peripheral alkyl chains, these polymers show different LC structures. The polymer with the terphenyl rigid side-chain core and relatively short alkyl tails is amorphous in the whole temperature range, while those with the same rigid side-chain core but longer alkyl tails exhibit columnar nematic (Coln) phases. Polymers with a longer rigid side-chain core and relatively long alkyl tails develop into smectic A (SmA) phases. In addition, the LC polymers obtained in this study display LC phases in wide temperature ranges. The experimental process involved the reaction of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate(cas: 1312703-30-2).Formula: C22H19NO4
