Comments on Inorganic Chemistry, 2009
This account describes the development of a new type of polymerization catalysis termed ion-pairing polymerization (IPP). IPP utilizes compatible and dually active transition-metal cation–main-group anion ion pairs in which both the cation and the anion can independently catalyze the polymer chain growth in a single polymerization reaction. Furthermore,

Proteins: Structure, Function, and Bioinformatics, 1987
AbstractA survey of 47 globular proteins was made to determine the probability of occurrence of ion pairs separated by 1, 2, 3, … and 8 residues in the alpha helices. As a control, the probability of occurrence of like charged pairs was also determined. The survey showed that ion pairs of the type i, i±3 and i, i±4 are the most predominant.

Journal of Chemical Theory and Computation, 2017
We present a theory for ion pair dissociation and association, motivated by the concepts of Marcus theory of electron transfer. Despite the extensive research on ion-pairing in many chemical and biological processes, much can be learned from the exploration of collective reaction coordinates.

High-performance ion-pair chromatography
Journal of Biochemical and Biophysical Methods, 1989Isolation of one or more minor components from a sample of biological origin is a very common task in biomedical and biochemical research. The problems met with in this kind of trace analyses are often highly intricate. The trace components must be isolated from a series of other organic compounds of a nature and a concentration which is known to a ...

Ion Pair Transport Across Membranes
Pharmaceutical Research, 1989The present review discusses drugs and counter ions suitable for ion pair transport (IPT). Ion pairing is shown to effectively increase the lipophilicity and transport rate of polar drugs across lipid membranes. The proposed mechanisms of IPT are discussed in detail. A marked change in drug properties upon ion pair formation is necessary to improve the

Ion-pair solid-phase extraction
Journal of Chromatography A, 2000Solid-phase extraction (SPE) is a technique widely employed by analytical chemists. SPE cartridges are available in a wide variety of formats containing media with diverse chemistries. This paper will review ion-pair SPE, one of the less frequently applied, and presumably less well-known techniques.

Polymerizable ion-paired amphiphiles
Langmuir, 1991Sonic-dispersal of N,N-dimethyl-N-octadecyl-N-(3-(1-acrylamido)propyl)ammonium stearate in water produces vesicules that range in diameter between 335 and 730 angstoems.

Journal of Physics and Chemistry of Solids, 1958
Abstract The occurrence of ion pairing in silicon is demonstrated. The pairing process is used to determine the diffusivity of lithium in silicon at low temperatures and the distance of closest approach between the ions forming the pair.
