Zusammenfassung:To provide novel compounds suitable as materials for organic devices such as organic EL elements.SOLUTION: A polycyclic aromatic compound is represented by formulae (1), (2), or (3). (Rings A to I are substituted or unsubstituted aryl rings, or substituted or unsubstituted heteroaryl rings, ZC is =C(-RC)- (RC is hydrogen or a substituent) or =N-, and at least one of rings A-G in the formulae (1), (2), and (3) includes a substituent represented by the formula (X), RX is a substituent, LX is a single bond or a divalent linking group, X1 to X4 are >N-RNX (RNX is aryl or the like)>O, or >S, and RNX may bind to one or two of rings combined with X1-X4).SELECTED DRAWING: None 【課題】有機EL素子等の有機デバイス用材料として有用な新規化合物を提供する。【解決手段】式(1)、式(2)、または式(3)で表される多環芳香族化合物;TIFF2024089626000207.tif52170(A環~I環は置換もしくは無置換のアリール環または置換もしくは無置換のヘテロアリール環、ZCは=C(-RC)-(RCは水素または置換基)または=N-であり、式(1)、式(2)、および式(3)各式中のA~G環の少なくとも1つは式(X)で表される置換基を含み、RXは置換基、LXは単結合または2価の連結基、X1~X4は>N-RNX(RNXはアリール等)>O、または>Sであり、RNXはX1~X4が結合する環の1つまたは2つと結合していてもよい。)【選択図】なし
