It is believed that voltammetry of undiluted red-ox liquids can lead to the formation of stable thin layers of ionic liquids at the microelectrode surface. Such situation was postulated for several liquids (solvents), however, so far no hard evidence

It is known that either a very strong enhancement or an almost complete depression of the height of one of two waves can be obtained when two analytes (one appropriately charged and one uncharged) are present in a quiet solution containing no support

The influence of stream orientation versus surface of microelectrode detector was examined in the range between vertical and parallel flow for various jet velocities and various levels of supporting electrolyte. The flow cell was equipped with a coni

Digital simulation of steady-state voltammetry of diffusion–migration systems with the reactant involved in the complexation reaction has been carried out using a FIFD-related algorithm. It has been found, that in the case of neutral ligands, the s

Three newly synthesized polyanthraquinone derivatives: 7,13-bis(9,10-dioxo-1-anthryl)-1,4,10-trioxa-7,13-diazacyclopentadecane, (AQ)A215C5, 7,16-bis(9,10-dioxo-1-anthryl)-1,4,10,13-tetraoxa-7,16-diazacyclooctadecane, (AQ)A218C6, and tris[(9,10-diokso

A simulation scheme, based on the fast implicit finite difference algorithm has been proposed for the modeling of steady-state voltammograms under conditions of mixed diffusion–migration transport in multi-ion systems. The scheme assumes the single

Steady-state currents of charged reactants, at a hemispherical ultramicroelectrode, are independent of the concentration of supporting electrolyte if the relationship zR/zP=DR/DP (R=ionic reactant, P=ionic product) is satisfied. Under the above condi

In the classic voltammetric approach to host--guest systems the investigations are carried out in excess of a supporting electrolyte, i.e., an inactive ionic salt. This approach ensures high electric conductivity of solution and ion migration is avoi

The complexation properties of new hosts consisting of two crown ethers connected by an anthracene group have been studied using spectrophotometry, fluorescence spectroscopy and cyclic voltammetry. The complexation and recognition properties of these
