An organic electroluminescent element material represented by Formula (1),
Formula (1):
wherein Z is a heterocylcic ring comprising a substituent having a steric parameter value (Es) of −0.5 or less at the third atom of the ring counted from a nitrogen atom attached to Z, the nitrogen atom being counted as the first atom; and other symbols in Formula (1) are described in the specification.
Catalytic cyclization via dual C–Hbondactivation has evolved as a powerful strategy for building bi- and polycyclic molecules. Herein, a palladium-catalyzed annulation of tertiary anilines with 3-butenoic acid via N-α-C(sp3)–H and ortho-C(sp2)–H activation is described. The remarkable characteristics of this reaction include excellent diastereoselectivity, broad substrate scope, and good tolerance

Disclosed is an organic electroluminescent device having high external quantum efficiency and long emission life. Also disclosed are an illuminating device and a display, each comprising such an organic electroluminescent device. The organic electroluminescent device is characterized by comprising at least an anode and a cathode on a supporting substrate, while having at least one light-emitting layer between the anode and the cathode. The organic electroluminescent device is also characterized by containing a polymer which at least partially contains a compound A having a partial structure represented by the general formula (a) below and a reactive group, and is obtained by polymerizing the compound A through the reactive group. (In the formula, Ar1 and Ar2 respectively represent an aromatic ring.)
