Title:
LIQUID ORGANIC SEMICONDUCTOR MATERIAL
Document Type and Number:
WIPO Patent Application WO/2011/034206
Kind Code:
A1
Abstract:
An organic material, which has at least one aromatic conjugated π-electron system in the structure, is selected and purified to increase the purity. Next, the conduction mechanism thereof is confirmed by the time-of-flight method. Thus, the organic material in a liquid phase can be used as an organic semiconductor. Disclosed is a method whereby an organic material, which has at least one aromatic conjugated π-electron system in the structure, in a liquid phase can be used as an organic semiconductor, said method comprising confirming the electron conductivity of the organic material by evaluating the charge transporting properties thereof by the time-of-flight method and evaluating the dilution effect in the case of adding a diluent thereto.
