HETEROCYCLIC COMPOUND AND LIGHT-EMITTING ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a compound useful as a material for various kinds of electronic devices, especially a light-emitting element and to provide the light- emitting element having excellent luminescent properties, preservation durability, etc. SOLUTION: The compound is represented by general formula (I) (R111, R112, R113, R114, R121, R122, R123, R124, R131, R132, R133, and R134are ach a halogen atom, an alkyl group or the like; R115, R116, R117, R118, R125, R126, R127, R128, R135, R136, R137and R138are each a hydrogen atom or the like; n11is 0 or 1; L11is an arylene group or the like; R111-R118, R121-R128and R131-R138may be mutually bonded to form rings with the proviso that a case in which n11is 1, R116, R126and R136are each an alkyl group except a primary alkyl group and R117, R127and R137are each an alkyl group is omitted). The light-emitting element is obtained by using the compound. COPYRIGHT: (C)2004,JPO
