Abstract Control of excited‐state dynamics is key in tuning room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) emissions but challenging for organic luminescent materials (OLMs). We show the regulation TADF RTP a boron difluoride β‐acetylnaphthalene chelate ( β CBF 2 ) by controlling via its J‐ H‐aggregation states. Two crystalline polymorphs emitting green red light have been controllably obtained. Although both monoclinic, crystals are dominated...
It is well-known that thermally activated delayed fluorescence (TADF) always generated from charge-transfer (CT) excited states in donor-acceptor (D-A) systems, which limits its application owing to a slow radiative process and small stimulated emission cross section. Herein, design strategy proposed for realizing TADF locally (LE) state without typical type structure through controlling the intersystem crossing (ISC) reverse (RISC) processes between lowest singlet with LE character higher...
Abstract Luminescence originated from singlet (S 1 ) and triplet (T states is categorized as fluorescence phosphorescence, respectively. Modulation of phosphorescence pathways plays a central role in developing organic luminescent materials, but remains difficult because the lack control ways. Here, luminescence cocrystals 1,7‐phenanthroline (PR) 1,4‐diiodotetrafluorobenzene (DITFB) can be switched by adjusting their stoichiometry, bluish for 1:0 pure PR crystal (P1D0) to yellowish 1:1...
Organic room-temperature phosphorescence (ORTP) has been demonstrated successfully in solids. In contrast, solution-phase ORTP is rarely achieved, because the T1 → S0 too slow to compete against nonradiative decay and oxygen-quenching effect. Here, we reported that suppression of Kasha's rule a strategy achieve from high-lying T2 state by spatially separating on different parts molecule (CzCbDBT) composed carbonyl (Cb), dibenzothiophene (DBT), carbazole moiety (Cz). On one hand, intersystem...
A novel organic TADF molecule SBF<sub>2</sub>BTF with good gain characteristics is designed and synthesized, the semiconductor laser based on a realized for first time in self-assembled two-dimensional single crystal microribbons.
Creating nano-to-macroscopic-sized artificial actuators in response to light has been a challenging issue. Herein, we describe the design, synthesis, and operation of photomechanical molecular crystal (PMMC) that exhibits well-controlled multiple photo-driven motions, including translation, rotation, jumping, by adjusting irradiation sites. Theoretical calculation discloses conversion energy into macroscopic motion occurs through conformation change between excited ground states mediated...

Abstract Organic gain materials (OGMs) currently used in dye lasers and organic thin‐film amplifiers are limited to singlet‐fluorescence molecules. Although heavy‐metal‐containing phosphorescent emitters enable highly efficient light‐emitting diodes, OGMs capable of light amplification by stimulated emission from triplet states remain largely unexplored. Demonstrated herein is the first laser a pure luminescent rotor ( 1 ), composed electron‐donating sulfide‐substituted difluoroboron (SBF 2...
Stem cell and tissue engineering-based therapies for acute liver failure (ALF) have been limited by the lack of an optimal source. We aimed to determine suitability human parthenogenetic embryonic stem cells (hPESCs) development strategies treat ALF. studied ability with high whole-genome SNP homozygosity, which were obtained natural activation during in vitro fertilization (IVF), differentiate into functional hepatocyte-like monolayer plane orientation. hPESCs induced on a single-layer flat...
As is well known, the thermally activated delayed fluorescence (TADF) always generated from charge-transfer (CT) excited states in electron-donor (D) – electron-acceptor (A) systems. Here, a novel design strategy proposed for realizing TADF locally (LE) state through controlling intersystem crossing (ISC) and reverse (RISC) processes between LE singlet higher triplet CT states. Based on strategy, boron difluoride derivative theoretically predicted to emit state, whose radiative decay rate...

Abstract Background Breast cancer has surpassed lung as the most common cancer. Day surgery for breast been widely carried out worldwide, but development of day in China is relatively slow. To reduce spread coronavirus 2019 (COVID-19), major centres have optimized management procedures to different degrees. However, relevant research on whether rapid turnover and excessive human resources placed prevention control COVID-19 epidemic will affect quality lacking. Method The demographic data,...
Jmjd6 is a conserved nuclear protein which possesses histone arginine demethylation and lysyl hydroxylase activity. Previous studies have revealed that essential for cell differentiation embryo development. However, the role of in mammalian ES identity reprogramming has been unclear. Here we report depletion not only results downregulation pluripotency genes but also implicated apoptosis, glycolysis, cycle hydroxylation. We reduction BrdU incorporation depleted cells.
