Abstract

The invention pertains to organic compounds of the tetrahiafulvalene type made amphiphillic by substitution of the radicals R.sup.1 and R.sup.2 meeting one of the following conditions: PA0 R.sup.1 is a hydrophilic group and R.sup.2 is a hydrophobic group, PA0 R.sup.1 is a hydrophobic group and R.sup.2 is a hydrophilic group, PA0 R.sup.1 is an aromatic group and R.sup.2 is a group having a long carbon-containing chain with a hydrophobic nature and a hydrophilic end. These organic compounds can form Langmuir-Blodgett films which are made anisotropically conductive by doping.
