Organic room-temperature phosphorescent (RTP) materials routinely incorporate polymeric components, which usually act as non-functional or "inert" media to protect excited-state phosphors from thermal and collisional quenching, but are lesser explored for other influences. Here, we report some exemplary "active roles" of polymer matrices played in organic RTP materials, including: 1) color modulation total delayed emissions via balancing the population ratio between thermally-activated...
Organic luminogens with persistent room-temperature phosphorescence (RTP) have found a wide range of applications. However, many RTP are prone to severe quenching in the crystalline state. Herein, we report strategy construct donor-sp3 -acceptor type luminogen that exhibits aggregation-induced emission (AIE) while donor-sp2 counterpart structure non-emissive solid Unexpectedly, it was discovered trace amount (0.01 %) structurally similar derivative, produced by side reaction DMF solvent,...
Room-temperature phosphorescence (RTP) polymers have important applications for biological imaging, oxygen sensing, data encryption, and photodynamic therapy. Despite the many advantages polymeric materials offer such as great control over gas permeability processing flexibility, disorder is traditionally considered an intrinsic negative impact on efficiency embedded RTP luminophores, various allowed thermal motions could quench emitting states. However, we propose that disorder-enabled...
Abstract Triphenylamine (TPA) was reported to exhibit temperature‐dependent dual phosphorescence, where the red‐shifted band assigned as excimeric phosphorescence with an energy shift of >3000 cm −1 ( J. Phys. Chem . 1991 , 95 7189). Here we show that purified TPA (purity: >99.97 %) shows a single small <200 under same experimental conditions. The new results, along theoretical calculations, suggest previously triplet excimer is probably not valid and most likely due unidentified...
Carbonyl groups in organic phosphors can significantly benefit the process of intersystem crossing (ISC) but may lead to rapid photodegradation. Recently, twisted molecules consisting an aromatic donor and acceptor free carbonyls have been used enhance ISC without unstable photochemistry. The strategy is thought be analogous El-Sayed rule, where electrons go through circular motions thus boost spin-orbit coupling (SOC) during photoexcitation. However, such a design has not systematically...
The magnetic van der Waals crystals MnBi2Te4/(Bi2Te3)n have drawn significant attention due to their rich topological properties and the tunability by external field. Although family been intensively studied in past few years, close relatives, MnSb2Te4/(Sb2Te3)n family, remain much less explored. In this work, combining magnetotransport measurements, angle-resolved photoemission spectroscopy, first principles calculations, we find that MnSb4Te7, n=1 member of is a system with versatile...
Acute kidney injury (AKI) is defined by a sharp decrease in the estimated glomerular filtration rate (eGFR). However, impact of medication history on survival AKI patients has received little attention. Hence, it necessary to investigate potential as predictor outcomes among intensive care unit (ICU). Critically ill were sourced from MIMIC-IV database. To ascertain significant, drug-related, independent predictors survival, univariate Cox analysis and stepwise regression performed. Based...
A new mutant of Escherichia coli K-12 unable to grow with L-serine, glycine, and L-leucine has been isolated by lambda plac Mu insertion shown be deficient in L-serine deaminase activity. The corresponding gene, sdaA, cloned from a prototrophic strain, the clone characterized sequenced. evidence is consistent hypothesis that sdaA structural gene for deaminase. However, other possibilities are also considered. No significant homology previously reported DNA or protein sequences was detected.
Solid polymer electrolyte (SPE) is one of the choices for many ionic devices, including organic transistors, ion batteries, memristors, and more. However, uncontrollable conductive filament formation seriously affects performance device. In this paper, PEDOT:PSS was doped to improve electronic conductivity amorphous poly(vinylpyrrolidone) (PVP), realizing transition filaments growth from cathode anode in atomic switch memristors. Based on difference electron mobility scanning microscope...

The ability to modulate luminescence is crucial for organic light-emitting molecules. However, the correlation between molecular structure and emission not always obvious systematic. Here, using a well-established empirical rule on electrophilic substitution involving directing groups in chemistry, we present model system, where two luminophores are covalently linked benzene ortho, meta, para each other, demonstrate that can also be useful predicting fluorescence phosphorescence behaviors of...
The MHC class II transactivator gene (CIITA) coordinately controls the expression of three major human genes, HLA-DR, HLA-DQ, and HLA-DP. Indeed, patients with one form immunodeficiency disease, due to defective CIITA lack all isotypes. Nevertheless, there is substantial evidence that genes are not always regulated, raising possibility CIITA-independent, isotype-specific regulatory pathways exist. To address this issue, we have generated a dominant negative mutant lacks acidic...
Domain generalization (DG) aims to create a model that is trained across multiple source domains and capable of performing well on new, previously unseen target domains. The essence this task lies in acquiring features are both discriminative invariant One common approach achieve through adversarial DG, with techniques like generative networks (GANs). However, these methods often struggle limited intraclass diversity, hindering their capabilities. To address this, we introduce the graph...
The interplay between various symmetries and electronic bands topology is one of the core issues for topological quantum materials. Spontaneous magnetism, which leads to breaking time-reversal symmetry, has been proven be a powerful approach trigger exotic phases. In this Letter, utilizing combination angle-resolved photoemission spectroscopy, magneto-optical Kerr effect microscopy, first-principles calculations, we present direct evidence on realization long-sought spontaneous...
