<p>PURPOSE: 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 R 1 -R 4 represents hydrogen, a C 1 -C 24 alkyl group or a C 1 -C 24 alkoxy group. Each of A 1 -A 5 represents hydrogen, a C 1 -C 24 alkyl group or a C 3 -C 24 cycloalkyl group. Each of B 1 and B 2 represents hydrogen, a C 6 -C 24 aryl group, a C 1 -C 24 alkyl group or a C 3 -C 24 cycloalkyl group. Each of X 1 -X 5 represents hydrogen, a C 1 -C 24 alkyl group or a C 3 -C 24 cycloalkyl group.</p> |
