OLIGO-TETRACENES, PRODUCTION AND USE THEREOF

摘要

The invention relates to oligo-tetracenes of formula (I) which are either unsubstituted or carry one or several substituents (R and R'), which are selected from the group which consists of halogen, CN, alkyl- or alkoxy radicals having 1 - 18 carbon atoms, aryl radicals having up to 12 carbon atoms which can also contain one or several heteroatoms and/or fluorinated or perfluorinated alkyl- or alkoxy radicals having 1 - 18 carbon atoms, wherein n is a whole number between 1 - 20, preferably 1 - 6, more preferably 1 or 2 and X represents an alklyene group having 1 6 carbon atoms, a hydrocarbon chain having one or several conjugated dual compounds, an aryl group or a system consisting of one or several condensed aromatic rings, for a single compound. In the inventive oligotetracenes, one or several of the six-atomic, condensed, aromatic rings can be replaced by a five-atomic ring which can contain a heteroatom. The invention also relates to a method for producing the known oligo-tetracenes and to the used thereof as a semi-conductor in organic field effect transistors (OFET), organic light-emitting diodes (OLEDs), sensors and organic solar cells.
