Thermally activated delayed fluorescence(TADF)materials with aggregationinduced emission(AIE)features can overcome aggregation-caused quenching(ACQ)and emit intensely in aggregate states and thus have attracted enormous attention in the fields of high-efficiency organic light-emitting diodes,bioimaging,photodynamic therapy,photocatalysis,***,their corresponding exact working mechanisms at the microscopic level are still far from ***,by carefully investigating the physical properties of our newly designed TADF material 6-(10H-spiro[acridine-9,9′-fluoren]-10-yl)nicotinonitrile in various states,we concluded that conformational isomerization plays an important role in realizing high photoluminescence quantum yields in its amorphous neat film state,in which the high-lying quasi-axial conformations with non-TADF features and low-lying quasiequal conformations with TADF characteristics serve as the host matrix and dopant,respectively,thus suppressing ACQ in disordered aggregate *** work not only offers a new possible microscopic mechanism by using conformational isomerization for the AIE-TADF phenomenon but also provides a novel method for designing high-efficiency AIE-TADF emitters.

Akkermansia muciniphila, one of the most promising next-generation probiotics, was reported to exhibit beneficial modulatory effects on the gut barrier. However, the strain-specific and underlying regulatory mechanisms of this species on gut barrier function were not well studied. Therefore, this study evaluated the protective effect of A. muciniphila strains on the intestinal barrier and investigated the mode of action and material basis of this modulatory effect. We first confirmed the strain-specific effects of A. muciniphila on intestinal barrier regulation and found that this phenomenon may be explained by the different abilities of strains to affect tight junction protein expression in enterocytes. Comparative genomic analysis proved that the ability of A. muciniphila to regulate the intestinal barrier was exerted in part by the functional genes(such as COG0438, COG0463, and COG2244)related to the synthesis of cellular surface proteins. The role of these surface proteins in intestinal barrier regulation was further verified by strain-comparative experiments in animal and cell models and surface protein removal trials. This study confirmed the different effects of A. muciniphila strains on gut barrier modulation and provided molecular and genetic targets for the screening of A. muciniphila strains with superior protection against gut barrier dysfunction.
