[{"publication":"Chemistry of Materials","extern":"1","abstract":[{"lang":"eng","text":"Periodically ordered mesoporous magnesium oxide was synthesized in a double replication procedure. Mesoporous SBA-15 silica and CMK-3 carbon were successively used as hard structure matrixes. The carbon pore system was infiltrated with Mg(NO3)2, which was then converted to MgO at 573 K; the carbon matrix was finally removed by thermal combustion. The structure of the mesoporous MgO corresponds to that of the original SBA-15 silica. The products consist of hexagonally arranged cylindrical mesopores and crystalline pore walls. The efficiency of the replication series was studied by variation of the infiltration method and comprehensive pore size analysis of all involved mesoporous materials. The in situ formation of MgO inside the CMK-3 carbon pore system was monitored by thermal analysis. Postsynthetic treatment of the products at 823 K in a vacuum prior to removal of the carbon matrix was found to improve the crystallinity but to diminish the periodic order of the pore system."}],"date_created":"2021-10-09T09:45:04Z","type":"journal_article","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"title":"Synthesis of Mesoporous Magnesium Oxide by CMK-3 Carbon Structure Replication","year":"2006","publication_identifier":{"issn":["0897-4756","1520-5002"]},"author":[{"first_name":"Jan","last_name":"Roggenbuck","full_name":"Roggenbuck, Jan"},{"first_name":"Günter","last_name":"Koch","full_name":"Koch, Günter"},{"orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael","full_name":"Tiemann, Michael","id":"23547"}],"publication_status":"published","date_updated":"2023-03-09T08:58:00Z","article_type":"original","language":[{"iso":"eng"}],"doi":"10.1021/cm060740s","citation":{"ieee":"J.

The underlying protocol can be used with predefined ureas as well as secondary amines to build up these units by reaction with phosgene if the ureas are otherwise unavailable. In the latter case, the resulting urea intermediates do not have to be isolated as the reaction proceeds further with additional phosgene to yield a chloroformamidinium chloride which is transformed into the bis‐guanidine functionality by subsequent reaction with a suitable primary diamine in the presence of triethylamine as an auxiliary base. This concept has been used to synthesise and characterise more then two dozen different bis‐guanidines based on 12 discrete monoguanidine units and seven different spacers. These spacers have been chosen such that the most important phenotypes have been dealt with and which range from rigid to more flexible scaffolds. In addition to spacers with no metal‐binding capabilities, other species containing further donor functions such as <jats:italic>N</jats:italic>‐methyldiphenyleneamine or pyridine‐2,6‐diyl have also been used. The substitution patterns of the guanidine residues can be classified into acyclic and cyclic types. Among the cyclic types, one subset is characterised by five‐ or six‐membered heterocycles containing both the amino nitrogen atoms and another one by individual N‐heterocyclic systems for each amino nitrogen. Structurally characterised examples are 2‐{2‐[2‐(tetramethylguanidi­no)ethoxy]ethoxy}‐1‐(tetramethylguanidino)ethane (TMG<jats:sub>2</jats:sub>doo) in its diprotonated form and 2,2′‐bis[2<jats:italic>N</jats:italic>‐(1,1′,3,3′‐tetramethylguanidine)]diphenyleneamine (TMG<jats:sub>2</jats:sub>PA) as wellas <jats:italic>N</jats:italic><jats:sup>1</jats:sup>,<jats:italic>N</jats:italic><jats:sup>3</jats:sup>‐bis(dimorpholinomethylene)propane‐1,3‐diamine (DMorphG<jats:sub>2</jats:sub>p) as free bases. For the permethylated bis‐guanidine derivatives, the barrier to rotation around the (C=N)<jats:sub>guanidine</jats:sub> bond has been determined by means of temperature‐dependent EXSY <jats:sup>1</jats:sup>H NMR spectroscopy to range between 54 and 79 kJ mol<jats:sup>–1</jats:sup> depending on the type of spacer.
