A pair of chiral aromatic-imide-based TADF emitters were conveniently constructed for the fabrication of highly efficient CP-OLEDs.

An electric field can drive electride-like superalkali Na(HCN)3Na (1) switches into superalkalides Na+(HCN)3Na− (2 and 3) via other superalkalides Na+(HCN)3Na− (2a and 3a) to form a SP4T NLO switch.

The superalkali electride e−⋯Li3+–PHY and superalkalide Liδ−–Li2(1–δ)−–PHY− show a good switchable effect.

Introduction Allergic fungal rhinosinusitis (AFRS) is characterized by refractory and high recurrence rate. Improper treatment may lead to repeated recurrence and even serious complications, including vision loss, blindness, and intracranial complications. However, AFRS is easy to be misdiagnosed clinically. Objective To ensure early diagnosis, the clinical presentations of patients with AFRS were studied. Methods Data from patients with sinusitis hospitalized in the First Affiliated Hospital of the University of Science and Technology of China (USTC) from January 2015 to October 2022 were collected. The patients were divided into three groups; group A patients with AFRS, group B patients suspected of AFRS, and group C patients with fungus ball sinusitis (FBS).We retrospectively analyzed the data using IBM SPSS 19.0 to perform the chi-square test and one-way ANOVA test. Results In total, 35 cases of AFRS, 91 cases of suspected AFRS, and 661 cases of FBS were rediagnosed. Compared with FBS patients, AFRS patients were younger, the total IgE, the percentage of eosinophils and basophils in peripheral blood were higher, and the proportion of patients with allergic rhinitis, asthma or hypo olfactory was higher. It had a higher recurrence rate. These results were also observed in the comparison between suspected AFRS patients and FBS patients, but no significant difference was found in the comparison between suspected AFRS patients and suspected AFRS patients. Conclusions and Significance AFRS may be misdiagnosed due to the low detection of fungi. To ensure early diagnosis, we recommend that patients with clinical, radiological, and laboratory features similar to those of AFRS but without evidence of fungal staining be treated according to the treatment criteria of AFRS.

For the stable superalkali-alkalide ion pairs in alkalide solutions, a DFT study was performed to investigate the nonlinear optics (NLO) responses of δ +(M-HMHC)-M’ δ - (M, M’ = Li, Na and K). The NLO responses display obvious alkali metal atomic number dependence (M’). From δ +(M-HMHC)-Li δ - to δ +(M-HMHC)-K δ -, the increases of the static and dynamic first hyperpolarizabilities constitute a 1 ∼ 3 orders of magnitude improvement.

A pair of novel circularly polarized thermally activated delayed fluorescence (CP-TADF) enantiomers (+)-(S,S)-CTRI-Cz and (−)-(R,R)-CTRI-Cz based on chiral triptycene scaffold were designed and synthesized. The obtained triptycene-derived enantiomers displayed obvious TADF activities with small singlet-triplet energy gap value (ΔEST) of 0.20 eV and characteristic microsecond delayed lifetime of 15.4 μs. Moreover, the TADF enantiomers showed mirror-image circular dichroism (CD) and circularly polarized luminescence (CPL) activities, and their luminescence dissymmetry factors (glum) were about ±0.9 × 10−3. Finally, by using the TADF enantiomers as emitters, the optimized organic light-emitting diodes (OLEDs) achieved maximum external quantum efficiency (EQEmax), current efficiency (CEmax) and power efficiency (PEmax) of 15.0%, 48.8 cd/A and 46.9 lm/W, respectively.
