Abstract:
In order to provide a novel π-conjugated compound capable of increasing the light-emission efficiency of an organic electroluminescence element, for example, this π-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; at least 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.)
