Summary:To provide a novel chrysene derivative excellent in heat stability and improved in carrier mobility as a semiconductor material constituting an organic EL element, specifically, as an electron transport material having a performance equal to or greater than that of TPBi being the conventional material and to provide an organic EL element using the chrysene derivative.SOLUTION: The chrysene derivative is represented by formula (1). [R1 to R12 each independently represent H, an aliphatic substituent, an aromatic substituent or an oligopyridine derivative such as 3,5-dipyridylphenyl group or the like].SELECTED DRAWING: None 【課題】有機ＥＬ素子を構成する半導体材料、具体的には、従来材料であるＴＰＢｉと同等以上の性能を有する電子輸送材料として、熱安定性に優れ、かつ、キャリア移動度の向上した新規クリセン誘導体、及び前記クリセン誘導体を用いた有機ＥＬ素子の提供。【解決手段】式（１）で表されるクリセン誘導体。［Ｒ１〜Ｒ１２は、各々独立にＨ、脂肪族置換基、芳香族置換基、又は、３,５−ジピリジルフェニル基等のオリゴピリジン誘導体］【選択図】なし
