To probe the efficient strategy for preparing a multifunctional sensing material, the facile synthesis strategies and successful examples are urgently required. Through the use of a hexadentate ligand derived from cyclotriphosphazene, which displays spiral configurations and multiple connection modes, a novel metal-organic framework (MOF) was constructed via 1-step synthesis from low-cost raw materials. The presence of multiple interaction sites decorating the helical channels of the reported MOF gives rise to exclusive solvochromic-sensing behavior for small ketone mols. such as acetone, acetophenone, and 2,5-diketohexane. Addnl., the helical structure of a Mn-carboxylate chain allows for the pore volume not only be available for the adsorption of large organic mols. but also enables the enantiopure selective separation of 1-phenylethanol (ee 35.99%). Also, the structural anal. of the acetophenone-encapsulated sample allowed the solvochromic mechanism to be elucidated, which should be ascribed to the strong H-bonding interaction between the guest mols. and specific sites on a host matrix. The exptl. results have not only clearly manifested the vital role of starting materials of MOFs, including the connection modes and spatial configuration, but also provided very valuable insight for the future assembly of novel multifunctional sensing materials. In the experiment, the researchers used many compounds, for example, (R)-2-Aminobutan-1-ol (cas: 5856-63-3Formula: C4H11NO).
(R)-2-Aminobutan-1-ol (cas: 5856-63-3) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Formula: C4H11NO
