Complex formation of fenchone with α-cyclodextrin: NMR titrations
13C NMR titration studies of inclusion complexes of bicyclic terpenoid, fenchone enantiomers with α-cyclodextrin revealed their 1:2 guest-host stoichiometry. Sequential binding constants were determined indicating a strong binding cooperativity of two α-cyclodextrin to fenchone. The overall association constants were used to calculate the Gibbs free energies of diastereomeric complex formation,...
متن کاملNMR methods for characterizing the pore structures and hydrogen storage properties of microporous carbons.
(1)H NMR spectroscopy is used to investigate a series of microporous activated carbons derived from a poly(ether ether ketone) (PEEK) precursor with varying amounts of burnoff (BO). In particular, properties relevant to hydrogen storage are evaluated such as pore structure, average pore size, uptake, and binding energy. High-pressure NMR with in situ H(2) loading is employed with H(2) pressure ...
متن کاملSingle-shot titrations and reaction monitoring by slice-selective NMR spectroscopy.
A new method, based on slice-selective NMR spectroscopy of inhomogeneous mixtures, is introduced to perform NMR titrations and reaction monitoring in a single experiment. The method was applied to the titration of a lithium salt with 12-crown-4, and to the reaction of nBuLi with N,N,N',N'',N''-pentamethyldiethylenetriamine (PMDTA).
متن کاملCharacterizing polygonality in biological structures.
Several systems involve spatial arrangements of elements such as molecules or cells, the characterization of which bears important implications to biological and physical investigations. Traditional approaches to quantify spatial order and regularity have relied on nearest neighbor distances or the number of sides of cells. The current work shows that enhanced performance can be achieved by con...
متن کاملMembrane-active aminophosphonates.
Xenobiotic exposure may induce cell membrane injury which would affect cellular structures and function. This study examined the influence of new aminophosphonates, synthesized for agrochemical application, on biological and model membranes properties. The aminophosphonates differed in the substituents on their carbon, nitrogen and phosphorus atoms. Measurements were made of the stability of pl...
