Abstract
ABSTRACT This is an addendum to our preceding article, ‘NMR pD-variation method to determine the proper stabilities of organic electrolyte complexes: case of histidine complexes with a cyclophane acid’ Supramolecular Chemistry https://doi.org/10.1080/10610278.2022.2134017, which proposes that the species distribution of complexes between organic electrolytes is determined by observing the pD dependence of NMR signals for a mixture of the reactants; the species distribution can be replotted in a pH scale. This addendum demonstrates that the process of data analysis is simplified even more reliably by employing a global fitting method in place of a local, successive method used previously; comparative evaluation was made using Excel® spreadsheets appended. The straightforward global analysis will facilitate the practice of pD-variation NMR titration. The application range is potentially extendable by the use of 13C NMR, which overcomes some weak points of the 1H NMR method. Grapical abstract
期刊介绍:
Supramolecular Chemistry welcomes manuscripts from the fields and sub-disciplines related to supramolecular chemistry and non-covalent interactions. From host-guest chemistry, self-assembly and systems chemistry, through materials chemistry and biochemical systems, we interpret supramolecular chemistry in the broadest possible sense. Interdisciplinary manuscripts are particularly encouraged. Manuscript types include: high priority communications; full papers; reviews, and; Methods papers, techniques tutorials highlighting procedures and technologies that are important to the field. We aim to publish papers in a timely fashion and as soon as a paper has been accepted and typeset it will be published in electronic form on the Latest articles section of the website. The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field. Under normal circumstances, Supramolecular Chemistry does not consider manuscripts that would be more suitable in a highly specialized journal. This includes, but is not limited to, those based mostly or exclusively on topics such as solid state/X-ray structures, computational chemistry, or electrochemistry. .
