PYRAN DERIVATIVES HAVING HIGH CARRIER TRANSPORTATION, LONG WAVE LENGTH OF LIGHT EMISSION, AND RED LIGHT EMISSION, METHOD FOR MANUFACTURING THE SAME, AND LIGHT-EMITTING ELEMENT CONTAINING THE SAME

摘要

PURPOSE: Pyran derivatives, a method for manufacturing the same derivatives, and a light-emitting element containing the same derivatives are provided, which pyran derivatives have high carrier transportation, long wave length of light emission, and red light emission, and easily form a membrane even if a large alkyl group is inserted into the pyran derivatives, so that a light-emitting device having low operation voltage and long wave length of light emission can be produced. CONSTITUTION: The pyran derivatives represented by formula (1) are provided, wherein A1 and A2 are independently C6-C16π-conjugated substituent; X1 is dialkylamino; and Y1 is diarylamino or alkylarylamino. The pyran derivatives represented by formula (2) are provided, wherein X2 is represented by formula (3); Y2 is represented by formula (4) or (5); Ar1 is C6-C14 aryl; R1 and R2 are the same or different, and independently C1-C4 alkyl; Ar2 is C6-C14 aryl; Ar3 and Ar4 are the same or different, and independently or optionally substituted aryl or cyclic residue; Ar5 is C6-C14 aryl; and Ar6 is optionally substituted aryl.
