Organic thin film materials with molecular ordering are gaining attention as they exhibit semiconductor characteristics. When using them for electronics, the thermal management becomes important, where heat dissipation is directional owing to anisotropic conductivity arising from ordering. However, it difficult evaluate anisotropy by simultaneously measuring in-plane and cross-plane conductivit...

Biodegradable strain sensors able to undergo controlled degradation following implantation have recently received significant interest as novel approaches detect pathological tissue swelling or non-physiological stresses. In this study, the physicomechanical, electrochemical and active pressure sensing behavior of an electrically conductive biodegradable poly(glycerol sebacate urethane) (PGSU) ...

A study on the polyvinylidene fluoride (PVDF) membrane using lignin and lignosulfonate oil palm empty fruit bunch (OPEFB) fillers have been carried out. This aims to determine additional effect of PVDF membrane. Lignin sulfonation has a good result proven by Fourier transform infrared spectra with peak at 1192 cm−1 which indicates sulfonate group. The degree was increased 8.9% for lignosulfonat...

UNLABELLED This work describes the potential of thin, spray-deposited, large-area poly(3,4-ethylenedioxythiophene)/poly(styrene-4-sulfonate) ( PEDOT PSS) conducting polymer films for use as transparent supercapacitor electrodes. To facilitate this, we provide a detailed explanation of the factors limiting the performance of such electrodes. These films have a very low optical conductivity of ...

A novel water-dispersible conducting polymer analogous to poly(3,4-dioxythiophene):polystyrene sulfonate (PEDOT:PSS) has been chemically synthesized in a single reaction in high yield. PEDOT:DS, a new member of the polythiophene family, is composed of a complex between PEDOT and the sulfonated polysaccharide polyanion dextran sulfate. Drop-cast films of aqueous suspensions of the material displ...

Poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) is a highly important and attractive conducting polymer as well commercially available in organic electronics, including electrochemical electronic chemosensors, due to its unique features such excellent solution-fabrication capability miscibility, high controllable conductivity, chemical stability, good optical transparency bio...

The reaction of 4-hy-droxy-pyridine and oleum produces 4-hy-droxy-pyridinium-3-sulfonate, C(5)H(5)NO(4)S, which shows delocalized bonds in the six-membered ring. In the crystal, adjacent zwitterions are linked by N-H⋯O and O-H⋯O hydrogen bonds into a layer motif. The crystal studied was a racemic twin.

In the crystal structure of the title compound, [Zn(C(5)H(4)NO(4)S)(2)(H(2)O)(2)], the 4-oxo-1,4-dihydro-pyridine-3-sulfonate anion chelates to water-coordinated zinc centres through the carbonyl O atom and through one O atom of the sulfonate group. The Zn(II) atom lies on a center of inversion, and adjacent mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional ne...

In the crystal structure of the title compound, [Mg(H(2)O)(6)](C(7)H(5)O(6)S)(2)·2H(2)O, the octa-hedral complex cation lies on an inversion centre and is hydrogen bonded through the coordinated water molecules to the substituted benzene-sulfonate monoanions and the water mol-ecules of solvation. These inter-actions together with a carb-oxy-lic acid O-H⋯O(sulfonate) association give a three-dim...

In the title p-toluene-sulfonate salt of the drug dapsone, C12H13N2O2S(+)·C7H7O3S(-), the dihedral angle between the two aromatic rings of the dapsone monocation is 70.19 (17)° and those between these rings and that of the p-toluene-sulfonate anion are 72.34 (17) and 46.43 (17)°. All amine and aminium H atoms are involved in inter-molecular N-H⋯O hydrogen-bonding associations with sulfonyl O-at...
