“…An electrochromic electrode based on viologen adsorbed onto a conducting support with low electrochemical capacitance typically shows colour changes suitable for display applications at charge densities of 1-2 mC/cm 2 . This observation can be related to the typically high specific absorbance coefficients for viologens around ε(λ max ) ≅ 10 4 L mol -1 cm -1 [17,18]. Depending on the purpose of a specific device application, the composition and size of the battery electrodes need to be dimensioned accordingly to support a sufficient number of operation cycles.…”

Short titleSelf-powered display for printed electronics AbstractThe growing market for flexible electronics devices is asking for reduction of manufacturing process complexity. One way to reduce complexity is to decrease the number of single components of a device by using integrated modules, i.e. device components providing multiple functions. In this article, the concept of a self-powered electrochromic graphics display device is demonstrated. The device is based on a three electrode system comprising an electrochromic electrode, a battery anode and a battery cathode, all in contact with a common electrolyte. The electrochromic electrode can be charged and discharged directly when connected to either the anode or cathode. Such a self-powered display integrates the functions of both a display and a battery. As part of a flexible electronics device, a self-powered display would be able to power other components, such as driver electronics.

Tailor‐Made Modification of a Gold Surface for the Chemical Binding of a High‐Activity [FeFe] Hydrogenase

Hydrogenases are iron–sulfur proteins that catalyze hydrogen turnover in a wide range of microorganisms. Three different classes have been described, and among these [FeFe] hydrogenases are the most active in H2 evolution. Hydrogenases are redox enzymes that have been shown to exchange electrons with graphite and modified noble metal electrodes. Making use of the latter, diffusible electron carriers are required to enable redox catalysis, as proteins do not specifically bind to the electrode surface. Diffusion‐limited electron transfer can be replaced by electron injection into immobilized hydrogenase by binding the redox mediator to the electrode surface. Here, we present the synthesis and spectroelectrochemical characterization of 1‐(10‐mercaptodecyl)‐1′‐benzyl‐4,4′‐bipyridinium dibromide (MBBP), which is used as redox‐active linker. CrHydA1, the high‐activity [FeFe] hydrogenase from Chlamydomonas reinhardtii, is immobilized on the linker‐modified gold electrode. Each surface modification step is controlled in situ by surface‐enhanced infrared absorption spectroscopy (SEIRAS). Functionality of the electrode–protein hybrid is demonstrated by recording the linker‐supported current. The specificcatalytic rate of hydrogen evolution by CrHydA1 (2.9 μmol H2 min–1 mg–1 hydrogenase) promises a valuable approach for further optimization of this novel bioelectrical interface.

“…N-hexyl-N 0 -(4-vinylbenzyl)-4,4 0 -bipyridinium bromide chloride was synthesized according to the method reported in the literature [20][21][22]. A mixed solution of 4,4 0 -bipyridine and hexylbromide (molar ratio 1.5:1) was heated at reflux in acetone for 24 h. The precipitate was washed with acetone, ether and then recrystallized from acetone.…”
