OLIGO-TETRACENES, PRODUCTION AND USE THEREOF

摘要

The invention relates to oligo-tetracenes of formula (I) (see 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.
