Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, is researched, Molecular C10H16O4, CAS is 560-09-8, about Enantiopure Metal-Organic Framework Thin Films: Oriented SURMOF Growth and Enantioselective Adsorption.Product Details of 560-09-8.
The LPE growth of [Zn2[(+)cam]2(dabco)n] [(+)cam = (1R,3S)-(+)-camphoric acid, dabco = 1,4-diazabicyclo[2.2.2]octane] and its enantiomeric form and their application to the direct QCM (quartz crystal microbalance) monitoring of the uptake of a pair of enantiomeric guest mols., namely (2R,5R)-2,5-hexanediol (R-HDO) and (2S,5S)-2,5-hexanediol (S-HDO) from the gas phase under flow conditions are described. As examined by surface X-ray diffraction in out-of-plane and in-plane modes, the SURMOFs (surface-attached MOFs) were grown in (110) and (001) orientations on SAMs of MHDA and PPMT, with MHDA = 16-mercaptohexadecanoic acid; PPMT = (4,(4-pyridyl)phenyl)methanethiol, resp., on Au-coated QCM substrates. The difference of absolute uptake and absorption rate for each of the chosen enantiomeric probe mols. R-HDO and S-HDO is clear, and show significant enantioselectivity.
