TL;DR: In this article, the authors modified the end groups of BTP-4F from IC-2F to CPTCN-Cl to achieve near optimal energy level match, resulting in higher open-circuit voltage (VOC) and power conversion efficiency (PCE).

TL;DR: In this paper, a small molecule acceptor of ITCPTC with thiophene-fused ending group was designed and synthesized by employing a new active methylene precursor of CPTCN.

TL;DR: In this article, a planar thermally activated delayed fluorescence (TADF) skeleton with two bulky carbazolyl units was used to enhance quenching resistance, and the steric effect largely removed the formation of detrimental excimers/aggregates, and boosted the performance of the corresponding devices with a maximum external quantum efficiency up to 40.3% with nearly unchanged emission spectrum.

TL;DR: In this article, the authors demonstrated a new approach enabling the emission spectra of MR emitters red-shift while retaining narrowband emission, and achieved the first narrowband yellow emitter with emission maxima of 562 nm and a full width at half-maximum (FWHM) of 30 nm.

TL;DR: In this paper, a new strategy to improve the performance of MR-TADF emitters by fusing sulfur element into the B-N based framework, aiming to utilize the non-metal heavy-atom effect in accelerating the reverse intersystem crossing (RISC) process of the emitter.
