Advanced Physics Research, EarlyView.Thermally Activated Delayed Fluorescence (TADF) is widely exploited to achieve high‐efficiency OLEDs. TADF Emitters are normally investigated with transient photoluminescence (PL), which requires the PL to be detected over multiple orders of magnitude in time and intensity.

Donor–Acceptor Fluorophores for Energy-Transfer-Mediated Photocatalysis [PDF]
, 2018 Triplet–triplet energy transfer (EnT) is a fundamental activation pathway in photocatalysis. In this work, we report the mechanistic origins of the triplet excited state of carbazole-cyanobenzene donor–acceptor (D–A) fluorophores in EnT-based ...

Chemistry – A European Journal, EarlyView.ABSTRACT Molecules that violate Hund's rule by exhibiting an inverted singlet–triplet gap (STG), where the first excited singlet (S1${\rm S}_1$) lies below the triplet (T1${\rm T}_1$), are rare but hold great promise as efficient fifth‐generation light emitters.

열활성지연형광 (TADF) 현상을 활용한 발광체의 합성, 광물리학적 특성 평가 및 전기발광 소자에의 활용 [PDF]
, 2023 학위논문(박사) -- 서울대학교대학원 : 공과대학 재료공학부, 2023. 2. 박수영.발광체는 유기 발광 다이오드와 관련된 주제들 중 가장 활발하게 논의되고 있을 정도로 유기 발광 다이오드에서 가장 중요한 역할을 수행한다. 기존의 형광체와 인광체의 시대를 지나, 열활성지연형광의 특성을 보이는 발광체들은 서로 다른 다중도를 갖는 들뜬 상태로부터 빛을 발생시켜야 하는 발광체의 한계점을 극복했다는 점에서 주목을 받고 있다.

Chemistry – A European Journal, EarlyView.Novel emissive liquid crystalline boron C,N‐chelates were prepared by integrating mesogenic units into the boron C,N‐core. Depending on the substituent at the boron, stable SmA or N mesophases were achieved while maintaining intense blue emission with excellent quantum yields (61%–100%).

Accounts of Chemical Research, 2018 Since the seminal work of Tang and Vanslyke in 1987 on small-molecule emitters and that of Friend and co-workers in 1990 on conjugated-polymer emitters, organic light-emitting diodes (OLEDs) have attracted much attention from academia as well as industry, as the OLED market is estimated to reach the $30 billion mark by the end of 2018.
