    • The present invention illustrates that materials containing indolizino[3,4,5-ab] isoindole with the structure B have excellent luminescence. The invention also shows a series of novel organic materials which include the structure of compound B. Each of these materials has also been found to have high luminescence. In addition, such materials have been found to have high luminescence at room temperature not only in solution, but also in the solid states. Among Materials A, it has been found that compounds with structures C and D and complexes with structure E have high luminescence quantum efficiencies and emit from blue to red light. Consequently, these compounds and complexes have high potentials for several optoelectronic devices, such as OLEDs, laser, sensor, and other semiconductor devices. It has also been found that the luminescence of complexes having the E structure include highly efficient phosphorescence at room temperature. This means the complexes of the E structure have high potential for OLEDs that use triplet excited states. Still another discovery is that OLEDs that include compounds and complexes that incorporate structure B, i.e., Materials A, show good performance in brightness, driving voltage, lifetime and pure chroma.
    • 本发明说明具有结构B的含吲哚唑并[3,4,5-ab]异吲哚的物质具有优异的发光性。 本发明还显示了一系列包括化合物B的结构的新型有机材料。这些材料中的每一种也被发现具有高发光性。 此外,已经发现这种材料在室温下不仅在溶液中而且在固态下具有高发光性。 在材料A中,已经发现具有结构C和D以及与结构E的配合物的化合物具有高的发光量子效率并且从蓝色到红色发射。 因此,这些化合物和配合物对于诸如OLED,激光,传感器和其它半导体器件的几个光电器件具有高电位。 还发现具有E结构的络合物的发光在室温下包括高效磷光。 这意味着E结构的复合物对于使用三线态激发态的OLED具有高的潜力。 另一个发现是,包括结合B,即材料A的化合物和配合物的OLED在亮度,驱动电压,寿命和纯色度方面表现出良好的性能。
