发光材料和使用其的有机电致发光器件

Luminescent material and organic electroluminescent device using the same
摘要：
To provide a luminescent material, especially one superior in blue light emission, which is used in an OEL device and allows the device to have higher luminescence efficiency, lower driving voltage, better thermal resistance and longer lifetime, as well as to provide an OEL device using the luminescent material. SOLUTION: A new luminescent material having an asymmetric structure with a basic anthracene skeleton is provided: In formula (1), each of R1—R4 represents hydrogen, a C1-C24 alkyl group or a C1-C24 alkoxy group. Each of A1-A5 represents hydrogen, a C1-C24 alkyl group or a C3-C24 cycloalkyl group. Each of B1 and B2 represents hydrogen, a C6-C24 aryl group, a C1-C24 alkyl group or a C3-C24 cycloalkyl group. Each of X1—X5 represents hydrogen, a C1-C24 alkyl group or a C3-C24 cycloalkyl group.
摘要（中）：

为了提供在OEL器件中使用的发光材料，特别是一种蓝光发光器件，并且允许器件具有更高的发光效率，更低的驱动电压，更好的热阻和更长的寿命，以及提供一种OEL器件 使用发光材料。 解决方案：提供具有基本蒽骨架的具有不对称结构的新型发光材料：在式（1）中，R 1 -R 4中的每一个代表氢，C C 1 -C 24烷基或C 1 -C 24烷氧基。 A 1 -O 5 - 中的每一个代表氢，C 1 -C 24烷基或C 1 -C 24烷基， 其中R 1，R 2，R 3，R 3，R 4， B 1和B 2中的每一个代表氢，C 6 -C 24 - 芳基，C 6 - C 1 -C 24烷基或C 3 -C 24环烷基。 X 1〜X 5中的每一个表示氢，C 1 -C 24烷基或C 1〜 其中R 1，R 2，R 3，R 3，R 4，
