The spectroelectrochemical behaviour of 1,4‐dimethoxypillar[5]arene (P5A) and its monomer in different organic solvents

Pillararenes were introduced as a novel class of macrocyclig host molecules in 2008 when 1,4-dimethoxypillar[5]arene (P5A) was synthesised. The pillararenes are similar in structure to the better known cyclodextrins or calixarenes and they can also form host-guest complexes with smallish molecules that can fit into their cavities. In a recent […]

Three-phase electrochemistry of a highly lipophilic neutral Ru-complex having tridentate bis(benzimidazolate)pyridine ligands

After a long haul, our paper describing three-phase experiments with a new hydrophobic Ru-complex redox-probe was finally published in Electrochimica Acta. This work is a collaboration between our group and Prof. Masa-Aki Haga’s at Chuo University in Tokyo. About two years ago Haga visited our institute and gave a talk, […]

Paper‐based electrochemical sensors and how to make them (work)

We just published a review-article in ChemElectroChem on paper-based electrochemical devices. Instead of a classic review of the published literature (of which there are plenty for paper-based devices) we opted to write a more practical guide for what to consider when making your first forays into the jungle of paper-based […]

Electrochemical reduction of 7,7,8,8-tetracyanoquinodimethane at the n-octyl pyrrolidone/water/electrode three-phase junction

Continuing our investigations of the behaviour of various redox probes at three-phase electrodes we have just published a paper looking at TCNQ (7,7,8,8-tetracyanoquinodimethane) in a standard droplet-based setup. The reason we choose TCNQ is that it’s a quinone related to the ones we studied in our previous publication on transfer […]

Best poster award for Karthika

Emilia, Marta, Magda W. and Karthika went to represent our group at the annual meeting of young scientists organized by the University of Silesia in Katowice under the banner Science Beyond Disciplines.  The organization committee did an amazing job! The conference cost was only 40 PLN including a very interesting workshop on the […]

Facilitated cation transfer at a three-phase junction and its applicability for ionophore evaluation

We’re on a roll. Another cation transfer paper was accepted1, also in Electrochimica Acta. This is work done by Marta and our undergrad student Julia. They were investigating transfer of cations at the three-phase junction driven by reduction of the fullerene C60 and facilitated by the addition of ionophores to […]

Electrochemistry of selected quinones at immiscible n-octyl-2-pyrrolidone/aqueous interface using a three-phase electrode system

Vishwanath’s research on cation transfer at a three-phase junction was just published1 in Electrochimica Acta. This paper looks at transfer of cations driven by a redox reaction in an organic droplet immobilised on the electrode surface. The droplet is small enough not to cover the whole electrode area, so a […]

Pencil Lead as a Material for Microfluidic 3D-Electrode Assemblies

After long, hard effort we finally published* our research on pencil lead electrodes as electrode arrays in a microfluidic system. This was first intended as an easy-to-assemble system that could be used e.g. in experiments for high-school students or undergrads. However, from that initial, simple idea it turned out to […]
