Derivatives having a heteroaromatic ring, a light emitting element thereof, the light emitting device, a lighting device and an electronic apparatus

2010 
The present invention relates to derivatives having a heteroaromatic ring, the light emitting element having a heteroaromatic ring derivative, the light emitting device, a lighting device and an electronic apparatus. One object of the present invention to provide a novel substance having excitation energy as bipolar heteroaromatic ring derivatives. Having a heteroaromatic ring derivative represented by the general formula to provide a (G1). In the formula, R11 to R20 each represent hydrogen, alkyl having 1 to 4, carbon atoms in the ring is an aryl group having 6 to 10. Further J represents a substituted or unsubstituted carbon atoms form a ring of the arylene group having 6 to 12. Further, α, β may be bonded to each other to form a carbazole skeleton. Further Het represents the general formula (S1-1) and general formula (S1-2) represents a substituent. In the general formula (S1-1) and general formula (S1-2), Ar1 to Ar4 each represent a substituted or unsubstituted carbon atoms form a ring of the aryl group having 6 to 10. R1 represents a hydrogen atom, alkyl having 1 to 4, carbon atoms in the ring is an aryl group having 6 to 10.
