Abstract Development of highly efficient circularly polarized organic light‐emitting diodes (CPOLEDs) has gained increasing interest as they show improved luminous efficiency and high contract 3D images in OLED displays. In this work, a series binaphthalene‐containing luminogenic enantiomers with aggregation‐induced emission (AIE) delayed fluorescence properties is designed synthesized. These molecules can emit from green to red light depending on the solvent polarity due twisted...
Three-dimensional ordered mesoporous/macroporous carbon sphere arrays (MMCSAs) are synthesized and then used as a catalyst for Li−O2 batteries. The hierarchical porous structure of the MMCSAs not only facilitates electrolyte immersion Li+ diffusion but also provides an effective space O2 O2/Li2O2 conversion, thus efficiently improves performance Li–O2 As service to our authors readers, this journal supporting information supplied by authors. Such materials peer reviewed may be re-organized...
Nitrogen-doped graphitic carbon materials hosting single-atom iron (Fe-N-C) are major non-precious metal catalysts for the oxygen reduction reaction (ORR). The nitrogen-coordinated Fe sites described as first coordination sphere. As opposed to good performance in ORR, that evolution (OER) is extremely poor due sluggish O-O coupling process, thus hampering practical applications of rechargeable zinc (Zn)-air batteries. Herein, we succeed boosting OER activity Fe-N-C by additionally...
The development of intelligent materials, in particular those showing the highly sensitive mechanoresponsive luminescence (MRL), is desirable but challenging. Here we report a design strategy for constructing high performance On-Off MRL materials by introducing nitrophenyl groups to molecules with aggregation-induced emission (AIE) characteristic. on-off methodology employed based on control intersystem crossing (ISC) process. Experimental and theoretical investigations reveal that group...

Herein, a visual sensing approach based on fluorescent imaging presented, by assembling aggregation-induced-emission (AIE)-active molecular rotors into moisture-captured network; resulting AIE are compatible with diverse applications, having tunable geometries desirable...
π-Extended helicenes constitute an important class of polycyclic aromatic hydrocarbons with intrinsic chirality. Herein, we report the syntheses π-extended [7]helicene 4 and [9]helicene 6 through regioselective cyclodehydrogenation in high yields, where a "prefusion" strategy plays key role preventing undesirable aryl rearrangements. The unique helical structures are unambiguously confirmed by X-ray crystal structure analysis. Compared to parent pristine [9]helicene, these novel display...
Abstract Humans and bacteria have always been closely related. However, pathogenic drug‐resistant pose a certain threat to human life health. On the other hand, probiotics, such as intestinal flora, also affect our daily life. Understanding microstructure of microorganisms is important for effective treatment bacterial infections. Luminogens with aggregation‐induced emission properties are now recognized potent fluorescent agents diagnosis microorganisms. In this review, we summarized most...
Aggregate is one of the most extensive existing modes matters in world. Besides research objectives inanimate systems physical science, entities life science can be regarded as living aggregates, which are far from being thoroughly understood despite great advances molecular biology. Molecular biology follows philosophy reductionism, generally reduces whole into parts to study. Although reductionism benefits understanding behaviors, it encounters limitations when extending aggregate level....
Cationic amphiphiles have been demonstrated to be superior targeted antibacterial agents whose activity exhibits a close relationship with their alkyl chain substituents. However, systematic and deep investigation of the structure–property is still pending. Meanwhile, cationic risk accumulating in living mammalian cells, which poses great threat biosafety clinical applications. In this study, series amphiphilic aggregation-induced emission luminogens (AIEgens) different chains (TPD-4, TPD-6,...

Heterocyclic polymers have gained enormous attention for their unique functionalities and wide applications. In contrast with the well-studied polymer systems five- or six-membered heterocycles, functional readily openable small-ring heterocycles rarely been explored due to large synthetic difficulty. Herein, a facile one-pot multicomponent polymerization such is developed. A series of multisubstituted heteroatom-rich azetidine frameworks are efficiently generated at room temperature in high...

Negatively curved nanographene (NG) 4, having two heptagons and a [5]helicene, was unexpectedly obtained by aryl rearrangement stepwise cyclodehydrogenations. X-ray crystallography confirmed the saddle-shaped structures of intermediate 3 NG 4. The favorability over helicene formation following radical cation or arenium mechanisms is supported theoretical calculations. 4 demonstrates reversible mechanochromic color change solid-state emission, presumably benefiting from its loose crystal...
