Purely organic materials showing room temperature phosphorescence (RTP) and ultralong RTP (OURTP) have recently attracted much attention. However, it is challenging to integrate circularly polarized luminescence (CPL) into RTP/OURTP. Here, we show a strategy realize CPL-active OURTP (CP-OURTP) by binding an achiral phosphor group directly the chiral center of ester chain. Engineering this flexible chain enables efficient chirality transfer carbazole aggregates, resulting in strong CP-OURTP...

Abstract Developing high-efficient afterglow from metal-free organic molecules remains a formidable challenge due to the intrinsically spin-forbidden phosphorescence emission nature of afterglow, and only few examples exhibit efficiency over 10%. Here, we demonstrate that can be enhanced dramatically by thermally activated processes release excitons on stabilized triplet state (T 1 * ) lowest singlet excited (S for spin-allowed emission. Designed in twisted donor–acceptor architecture with...

Summary Purple carrots, the original domesticated accumulate highly glycosylated and acylated anthocyanins in root and/or petiole. Previously, a quantitative trait locus (QTL) for root‐specific anthocyanin pigmentation was genetically mapped to chromosome 3 of carrot. In this study, an R2R3‐MYB gene, namely DcMYB113 , identified within QTL region. expressed ‘Purple haze’, carrot cultivar with purple nonpurple petiole, but not roots two cultivars petiole (Deep Cosmic purple) orange...

Achieving single-component white organic afterglow remains a great challenge owing to the difficulties in simultaneously supporting long-lived emissions from varied excited states of molecule for complementary afterglow. Here, an extraordinary tri-mode emission radiative decays singlet (S1 ), triplet (T1 and stabilized (T1* ) was proposed afford through modulating singlet-triplet splitting energy (ΔEST exciton trapping depth (ETD ). Low-lying T1 * yellow constructed by H-aggregation...

Abstract π‐Stacked dendrimers consisting of cofacially aligned donors and acceptors are developed by introducing three dendritic teracridan with orthogonal configuration triazine in periphery hexaphenylbenzene skeleton. The structure not only make their outer acridan segments approaching to acceptor close distance, but also fix donor face‐to‐face alignment, leading through‐space charge transfer emission thermally activated delayed fluorescence (TADF) effect. By regulating strength via...

Introduction Medial Opening-wedge High Tibial Osteotomy (HTO) is an effective treatment for medial compartment osteoarthritis and knee varus in relatively young active patients. While it can effectively correct lower limb alignment the coronal plane, may also affect posterior tibial slope (PTS) sagittal plane. However, factors influencing PTS methods maintaining stability remain controversial. Methods A geometric model was constructed based on CT data from a patient with knee. Multiple...
