Described are oligotetracenes of formula I which may either be unsubstituted or carry one or more substituents R and
R′ which are selected from the group comprising
halogen,
CN,
alkyl or alkoxy radicals containing 1 to 18 carbon atoms,
aryl radicals containing up to 10 carbon atoms which may also contain one or more
heteroatoms, and/or
fluorinated or perfluorinated alkyl or alkoxy radicals containing 1 to 18 carbon atoms,
where n is an integer from 1 to 20, preferably 1 to 6, very particularly preferably 1 or 2, and X stands for a single bond, an alklyene group containing 1 to 6 carbon atoms, a hydrocarbon chain having one or more conjugated double bonds, an aryl group, or a system composed of one or more condensed aromatic rings. In the oligotetracenes according to the invention, one or more of the condensed aromatic six-atom rings may be substituted by a five-atom ring which may also contain a heteroatom.
Also described is a method for preparing the referenced oligotetracenes, and use thereof as semiconductors in organic field-effect transistors (OFET's), organic light-emitting diodes (OLED's), sensors, and organic solar cells.
描述了具有式I的寡四环芳烃,它们可以是未取代的,也可以携带一个或多个取代基R和R′,这些取代基选自包括卤素、CN、含有1至18个碳原子的烷基或烷氧基基团、含有多达10个碳原子的芳基基团(也可能包含一个或多个杂原子)、和/或含有1至18个碳原子的氟化或全氟化烷基或烷氧基基团的群中,其中n是1至20的整数,优选为1至6,特别优选为1或2,X代表单键、含有1至6个碳原子的烷基基团、具有一个或多个共轭双键的碳氢链、芳基基团,或由一个或多个缩合芳香环组成的体系。根据本发明的寡四环芳烃中,一个或多个缩合芳香六元环可能被一个可能还含有杂原子的五元环取代。还描述了一种制备所述寡四环芳烃的方法,以及其作为有机场效应晶体管(OFET)、有机发光二极管(OLED)、传感器和有机太阳能电池中的半导体的用途。
