The present invention relates to the use of dibenzofurans and dibenzothiophenes which have at least one nitrogen-bonded five-membered heterocyclic ring as a substituent as host, blocker and/or charge transport material in organic electronics. The present invention further relates to dibenzofurans and dibenzothiophenes which comprise at least one nitrogen-bonded five-membered heterocyclic ring and at least one carbazolyl radical as substituents, to a process for preparation thereof, and to the use of these compounds in organic electronics.
本发明涉及在有机电子器件中将至少含有一个氮键合的五元杂环环作为取代基的二苯并呋喃和二苯并噻吩用作主体、阻挡剂和/或电荷传输材料。本发明还涉及至少含有一个氮键合的五元杂环环和至少一个咔唑基团作为取代基的二苯并呋喃和二苯并噻吩,以及其制备方法和在有机电子器件中的应用。
