ECD spectroelectrochemistry: A review

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2021
The electronic circular dichroism (ECD) spectroscopy is probably the most important chiraloptical method, and the role of chirality in contemporary chemistry, pharmacy, and material science constantly increases. On the other hand, the electrochemical methods are also very sensitive tools for studying multivarious redox processes.

Voltammetry and Spectroelectrochemistry of TCNQ in Acetonitrile/RTIL Mixtures

Molecules, 2020
Understanding the solvation and ion-pairing interactions of anionic substrates in room-temperature ionic liquids (RTIL) is key for the electrochemical applications of these new classes of solvents.

Bidimensional Spectroelectrochemistry

Analytical Chemistry, 2001
A new methodology is presented to offer the possibility of simultaneously obtaining two different spectroscopic signals in a single spectroelectrochemical experiment. Taking the plane of the electrode surface as a spatial reference, normal-beam and parallel-beam UV-vis absorbance signals are jointly analyzed, revealing important experimental ...

Totally synthetic microperoxidase-11 [PDF]

Royal Society Open Science, 2018
A totally synthetic microperoxidase-11 (MP-11) is reported. Accordingly, the undecapeptide (VQKCAQCHTVE) was synthesized by solid-phase peptide synthesis followed by the thiol-ene click reaction with haemin for reconstitution.

Bis(Triphenylamine)Benzodifuran Chromophores: Synthesis, Electronic Properties and Application in Organic Light-Emitting Diodes

Frontiers in Chemistry, 2021
A series of bis(triphenylamine)benzodifuran chromophores have been synthesized and fully characterised. Starting from suitably functionalized benzodifuran (BDF) precursors, two triphenylamine (TPA) moieties are symmetrically coupled to a central BDF unit

Electrosynthesis and Characterization of an Electrochromic Material from 2-(3-Thienyl)ethyl acrylate

International Journal of Electrochemical Science, 2015
A novel acrylate modified 3-thienylethanol (TE) was synthesized and its electropolymerization led to the formation of corresponding acrylate modified poly(3-thienylethanol) (PTE-AA).

Electrochemical Switch‐On of Nonlinear Optical Response in a Nitro‐Functionalized Arylimido‐Polyoxometalate

Angewandte Chemie, EarlyView.
Reducing a nitro‐derivatized arylimido‐polyoxometalate (POM) reversibly switches on its second‐order NLO response, contrasting with prior donor‐functionalized systems that switch off upon reduction. Attenuation of charge‐transfer (CT) to the POM upon reduction gives a more strongly dipolar imido/π‐bridge to ─NO2 CT, signal enhancement of up to 15× (β ...

Spectroelectrochemical Determination of Isoprenaline in a Pharmaceutical Sample

Sensors, 2020
UV/Vis absorption spectroelectrochemistry (SEC) is a multi-response technique that has been commonly used for the characterization of materials and the study of reaction mechanisms. However, it has been scarcely used for quantitative purposes. SEC allows
