Oral supplementation of myoinositol: effects on peripheral nerve function in human diabetics and on the concentration in plasma, erythrocytes, urine and muscle tissue in human diabetics and normals *

ABSTRACT‐ 28 young diabetics with short disease duration participated in a double‐blind study by taking 6 g of myoinositol or placebo daily for 2 months. The aim was to demonstrate a possible beneficial effect of this compound on subclinical diabetic neuropathy.

‘Organic metals’. Isostructural tetrathia- and tetraselena-fulvalene salts of 2,5-diethyltetracyano-p-quinodimethane

Replacement of the sulphur atoms in the charge transfer salt tetrathiafulvalene (TTF)–2,5-diethyltetracyano-p-quinodimethane (DETCNQ) with selenium yields the isostructural and better conducting analogue tetraselenafulvalene (TSeF)–DETCNQ, in which the Peierls transition temperature is decreased.

Organic conductors. 2,3,6,7-Tetramethyl-1,4,5,8-tetraselenafulvalenium 2,5-dimethyl-7,7′,8,8′-tetracyano-p-quinodimethanide

2,3,6,7-Tetramethyl-1,4,5,8-tetraselenafulvalene reacts with 2,5-dimethyl-7,7′,8,8′-tetracyano-p-quinodi-methane to give a highly conducting organic solid.

Molecular Properties of the Molecules used in Conducting Organic Solids

In this paper we shall try to communicate some of the ideas the organic chemist may utilize when trying to develop new conducting organic solids. First, we want to point out some important properties of typical organic molecules and try to show that if we want to form conducting solids, we are forced into working with certain classes of molecules. This in turn determines the special properties of the resulting solids.

‘Organic metals’: acceptor stack doping in the charge-transfer salt tetraselenafulvalene–tetracyano-p-quinodimethane (TSeF–TCNQ)

Doping of methyltetracyano-p-quinodimethane into the ‘organic metal’ tetraselenafulvalene–tetracyano-p-quinodimethane obscures the phase transition at 28 K and increase the conductivity at 4 K by four orders of magnitude.
