Abstract

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.
