Zusammenfassung:	The present invention relates to a novel thermally activated delayed fluorescence (TADF) compound capable of controlling a through space charge transfer (TSCT), and an organic light emitting device (OLED) comprising the same and, more specifically, to: a novel TADF compound including a back bone capable of controlling a TSCT and enabling a color tuning selectively by adjusting a distance and a type between a donor and an acceptor and controlling a bandgap; and an organic light emitting device including the TADF compound. 본 발명은 공간 전하 이동(Trough Space Charge Transfer; TSCT) 조절이 가능한 신규한 열활성화 지연 형광(Thermally Activated Delayed Fluorescence; TADF) 화합물 및 이를 포함하는 유기발광소자(Organic Light Emitting Device; OLED)에 관한 것으로, 더욱 상세하게는 상기 TADF 화합물은 공간 전하 이동 조절이 가능한 백본(backbone)을 포함하며, 도너(donor)와 억셉터(acceptor) 간의 거리 및 종류를 조절하여, 밴드갭(bandgap)을 조절함으로써 선택적으로 컬러 튜닝을 가능하게 하는 신규한 TADF 화합물 및 이를 포함하는 유기발광소자에 관한 것이다.
