Abstract
This benzonitrile derivative has the structure represented by general formula (1). [In the formula, each of substituent groups D1-D5 independently represents a carbazolyl group, and at least one thereof has a structure having a chirality-producing section. However, there is no case in which D1-D5 are all the same. Each of D1-D5 may independently further have a substituent group.]
Claims14
A benzonitrile derivative having a structure represented by the following Formula (1),
- in Formula (1), substituents D1 to D5 each independently represent a carbazolyl group, and at least one of D1 to D5 contains a structure having a chirality producing section, provided that not all of D1 to D5 are the same, and D1 to D5 each may independently further have a substituent.
