“…By the year 2006, when we initiated our potentiometric work on using metallabis(dicarbollides) to generate electroactive salts for the selective determination of amine-containing relevant drugs, two key experimental data were known for synthetic boron cluster chemists that were very relevant to start this research: the water insolubility of salts of Cs, used for Cs + sensing [ 28 ] and alkylammonium with anionic boron clusters and that these same salts were soluble in organic solvents like THF. This concept has been utilized with another series of closo boranes, e.g., tetradecylammonium triethylammonium- closo -dodecaborate as the electroactive species to determine [B 12 H 11 N(C 2 H 5 ) 3 ] − [ 29 ], or the use of the sulfonium derivative of the closo -hydridodecaborate anion [B 10 H 9 S(C 18 H 37 ) 2 ] − as the active component for a potentiometric lidocaine-selective sensor [ 30 ]. Concerning the use of the closo borate clusters the 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12-undecabromocarborane anion, [1-HCB 11 Br 11 ] − has been studied as an alternative to the best lipophilic tetraphenylborate, 3,5-[bis(trifluoromethyl)phenyl]borate demonstrating a much higher persistence in the potentiometric membrane [ 31 ].…”

This work is a mini-review highlighting the relevance of the θ metallabis(dicarbollide) [3,3′-Co(1,2-C2B9H11)2]− with its peculiar and differentiating characteristics, among them the capacity to generate hydrogen and dihydrogen bonds, to generate micelles and vesicles, to be able to be dissolved in water or benzene, to have a wide range of redox reversible couples and many more, and to use these properties, in this case, for producing potentiometric membrane sensors to monitor amine-containing drugs or other nitrogen-containing molecules. Sensors have been produced with this monoanionic cluster [3,3′-Co(1,2-C2B9H11)2]−. Other monoanionic boron clusters are also discussed, but they are much fewer. It is noteworthy that most of the electrochemical sensor species incorporate an ammonium cation and that this cation is the species to be detected. Alternatively, the detection of the borate anion itself has also been studied, but with significantly fewer examples. The functions of the borate anion in the membrane are different, even as a doping agent for polypyrrole which was the conductive ground on which the PVC membrane was deposited. Apart from these cases related to closo borates, the bulk of the work has been devoted to sensors in which the θ metallabis (dicarbollide) [3,3′-Co(1,2-C2B9H11)2]− is the key element. The metallabis (dicarbollide) anion, [3,3′-Co(1,2-C2B9H11)2]−, has many applications; one of these is as new material used to prepare an ion-pair complex with bioactive protonable nitrogen containing compounds, [YH]x[3,3′-Co(1,2-C2B9H11)2]y as an active part of PVC membrane potentiometric sensors. The developed electrodes have Nernstian responses for target analytes, i.e., antibiotics, amino acids, neurotransmitters, analgesics, for some decades of concentrations, with a short response time, around 5 s, a good stability of membrane over 45 days, and an optimal selectivity, even for optical isomers, to be used also for real sample analysis and environmental, clinical, pharmaceutical and food analysis.

Besides, some organic species bearing charge or able to protonate/deprotonate have been determined with the IL based potentiometric sensors (triethylammonium- closo -dodecaborate; Kopytin et al, 2012 ; Faridbod and Shafaat, 2017 ). In some of them, ILs are used as binding material in rather complex matrix consisting of ionophores and redox active species.…”

Solid Contact Potentiometric Sensors Based on a New Class of Ionic Liquids on Thiacalixarene Platform

et al. 2018

New solid-contact potentiometric sensors have been developed for hydrogen phosphate recognition on the basis of ionic liquids containing tetrasubstituted derivatives of thiacalix[4]arene in cone and 1,3-alternate conformations with trimethyl- and triethylammonium fragments at the lower rim substituents. The recognition of selected anions including carbonate, hydrogen phosphate, perchlorate, oxalate, picrate, and EDTA was conducted using electrochemical impedance spectroscopy with ferricyanide redox probe. For the potentiometric sensor assembling, the ionic liquids were stabilized by multiwalled carbon nanotubes and carbon black deposited on the glassy carbon electrode. The influence of support, steric factors and modification conditions on the sensor performance has been investigated. As was shown, potentiometric sensors developed make it possible to selectively determine hydrogen phosphate anion within the concentration range from 1 × 10−2 to 1 × 10−6 M and limit of detection of 2 × 10−7−1 × 10−6 M with unbiased selectivity coefficients varied from 1.2 × 10−1 to 1.0 × 10−8 (carbonate, acetate, oxalate, succinate, glutharate, glycolate, and malonate anions).
