ELECTROLUMINESCENT MATERIAL |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an organic electroluminescent element using a compound having a biaryl group including a bond axis which may give internal isomerization property. <P>SOLUTION: An electroluminescent material is represented by general formula (B1) (wherein Ar<SB>41</SB>and Ar<SB>42</SB>are each independently an aryl group or an aromatic heterocyclic group; L<SB>13</SB>is =N-, -N(R41)-, or -S-; L<SB>11</SB>and L<SB>12</SB>are atom groups necessary for forming a five-membered aromatic heterocyclic ring; R<SB>41</SB>is a hydrogen atom and the like; and at least one of Ar<SB>41</SB>, Ar<SB>42</SB>, and R<SB>41</SB>is a biaryl group having a bond axis capable of giving internal isomerization property or a group having the moiety of the biaryl group). <P>COPYRIGHT: (C)2011,JPO&INPIT |
