The present invention relates to a method for the deposition of at least one layer of an organic material on a substrate by (a) providing a source of a solid organic material in an atmosphere at a pressure comprised between 50 and 200 kPa, (b) heating said organic material to a first temperature to produce a vapor of said organic material, (c) exposing at least one surface of a substrate having a second temperature lower than said first temperature to said vapor to deposit organic material from said vapor onto said at least one surface of said substrate.

Method for the deposition of an organic material

Disclosed are a novel semiconductor composition comprising at least one organic semiconductor in a liquid medium and the use thereof the production of organic semiconductor devices, in particular organic field effect transistors, organic solar cells, light-emitting diodes and sensors.
