摘要：
本发明的课题在于，提供一种例如可以改良有机电致发光元件的发光效率的新型的π共轭类化合物。为了解决该课题，提供具有下述通式(1)所表示的结构的π共轭类化合物。(通式(1)中，Z1～Z6分别表示氢原子、氘原子、供电子基团D或吸电子基团A，Z1～Z6中的至少两个的一个为所述供电子基团D，另一个为所述吸电子基团A，且Z1～Z6中的邻位的组合Z1和Z2、Z2和Z3、Z3和Z4、Z4和Z5、Z5和Z6、及Z6和Z1的至少一个为所述供电子基团D和所述供电子基团D、所述吸电子基团A和所述吸电子基团A、或所述供电子基团D和所述吸电子基团A的组合的任一种)。
摘要（英）：

In order to provide a novel Pi-conjugated compound capable of increasing the light-emission efficiency of an organic electroluminescence element, for example, this Pi-conjugated compound has a structure indicated by general formula (1). (In general formula (1): Z1-Z6 each independently indicate a hydrogen atom, a deuterium atom, an electron-donating group D, or an electron-withdrawing group A; atleast out of two among Z1-Z6 is an electron-donating group D and the other is an electron-withdrawing group A; and at least one ortho position combination Z1 and Z2, Z2 and Z3, Z3 and Z4, Z4 and Z5, Z5 and Z6, or Z6 and Z1 among Z1-Z6 is one combination out of an electron-donating group D and an electron-donating group D, an electron-withdrawing group A and an electron-withdrawing group A, or an electron-donating group D and an electron-withdrawing group A.)
