Novel compounds containing substituted oligoazacarbazole chains are provided. Y- X-Z, wherein Y is selected from the group consisting of: A- B -C-D- A -B-C- A-B- wherein A, B, C, and D are independently selected from the compound of formula (I) wherein X is an aryl or heteroaryl linker that is optiorially further substituted; wherein Y and X are connected through a C—N bond; and wherein Z is selected from the group consisting of dibenzothiphene, dibenzofuran, dibenzoselenophene, aza-dibenzothiophene, aza-dibenzofuran, and aza-dibenzoselenophene that is optionally further substituted. These compounds are useful in organic light emitting devices, in particular as hosts in the emissive layer of such devices.
提供含有取代寡聚氮杂咔唑链的新化合物。Y-X-Z,其中Y从以下组中选择:A-B-C-D-A-B-C-A-B-其中A、B、C和D分别从式(I)的化合物中选择,其中X是一种芳基或杂芳基连接物,可以选择进一步取代;其中Y和X通过C-N键连接;Z从二苯并噻吩、二苯并呋喃、二苯并硒啶、氮杂二苯并噻吩、氮杂二苯并呋喃和氮杂二苯并硒啶中选择,可以选择进一步取代。这些化合物在有机发光器件中非常有用,特别是作为这些器件发射层中的宿主。
