Summary: Surface chemical regulation strategy can enhance the chemiluminescence (CL) performance of carbon nanodots (CDs), with optimized CD showing higher brightness and quantum yield compared to the initial CDs. This improvement is attributed to the decreased electron capture from water molecules generated during the CL process.

Summary: This paper reports the synthesis, purification, and characterization of chiral carbon nanodots using atropoisomeric precursors. The obtained carbon nanodots are soluble in organic solvents and exhibit good thermal stability, making them suitable for technological applications. By incorporating axially chiral precursors and 1,4-benzoquinone as a doping agent, green-emissive carbon dots with circularly polarized luminescence are achieved. The introduction of axial chirality expands the strategies for tailoring the properties of carbon nanodots, enabling the development of carbon nanoparticles with both good processability in organic solvents and engineered chiroptical properties.

Summary: Red emissive carbon dots (BNCDs), based on 1,1'-binaphthyl-2,2'-diamine (BNDM) and citric acid as a carbon source, were prepared through a one-pot solvothermal method. The synthesized BNCDs have uniform size distribution, photobleaching resistance, and show emission performance that is independent of the excitation wavelength. Moreover, the BNCDs exhibit bright red emission in a composite film with polyvinyl alcohol (PVA) matrix and the optical behavior can be tuned by changing solvent polarity. Additionally, BNCDs can serve as a fluorescence sensor for highly sensitive quantitative detection of trace water in organic solvents and as a fluorescence sensor for detection of Fe3+ and F-.

Summary: This work demonstrates a solvent-free large scale synthesis method for CDs with high QY, tunable PL emission, and production yield. The optical properties of the CDs can be modulated by controlling the deamination and dehydrogenation processes during reactions. Additionally, WLEDs with high CRI across the visible range are successfully fabricated by mixing the red, green, and blue emissive CDs into PVA matrix in appropriate ratios.

Summary: Emissive Cu(I) complexes with various ligands have been synthesized in the past two decades, exhibiting interesting and useful photophysical properties such as high luminescence efficiency, thermally-activated delayed fluorescence, stimuli-responsive emission, and excellent photochemical properties. These properties have found applications in light-emitting devices, sensors, and photocatalytic reactions. Studies on Ag(I) complexes have shown that strongly-emissive Ag(I) complexes can also be obtained using ligands similar to Cu(I) complexes.

Summary: Graphene quantum dots with tunable fluorescence emission, especially N-doped GQDs, were successfully synthesized from glucose and ethylenediamine using a microwave-assisted hydrothermal method. The N-GQDs exhibited fluorescence in the visible spectral region, extending to near-UV and slightly near-IR. The study also revealed the influence of band-to-band transitions, size effect, and nitrogen/oxygen functional groups on the multicolor emission of N-GQDs.

Summary: Understanding intrinsic wetting properties at solid/liquid interfaces at the molecular level is crucial in various fields. Surface wettability is not only determined by surface chemical composition and topography, but also by molecular structures, interactions, and the orientations of adsorbed interfacial water molecules. This study provides insights for improving wetting theoretical models and designing controllable wettability at the molecular/atomic level.

Summary: Different from conventional piezochromic materials, our designed molecule exhibits sensitive and tunable luminescence in response to hydrostatic pressure. The molecule possesses dual-emission and bidirectional shifting characteristics. Experimental studies reveal that the dual-emission behavior is attributed to intramolecular charge transfer and intermolecular excimer. The color change of the molecule from sky-blue to green to deep-blue is a result of intramolecular and intermolecular energy-transfer interactions.

Summary: Efficient warm white light emission is sought after in single-component materials for light-emitting applications. This study observed an unusual pressure-induced warm white emission enhancement in 2D perovskite (2meptH(2))PbCl4, accompanied by a significant increase in photoluminescence quantum yield. The collapse of the crystal structure triggered by octahedral distortions and the evolution of organic cations led to the emission enhancement, and further collapse promoted the formation of self-trapped excitons and suppressed nonradiative transitions, resulting in continuous photoluminescence enhancement under pressure.

Summary: This study introduces a flex-activated mechanophore (FA) that releases fluorescent anthracenes through a retro-Diels-Alder mechanochemical reaction under compression or hydrostatic high pressure. The force delivered to the mechanophore can be modulated by varying the crosslinking density of the networks and the applied macroscopic pressures, leading to incremental increases in mechanophore activation, successive release of anthracenes, and quantitative enhancement of fluorescence intensity. The exceptional potential of FA as a sensitive force probe in different bulk states is highlighted.

Summary: High sensitivity and multi-mode optical pressure sensing were achieved for the first time by co-doping Eu2+ and Mn2+ ions in the Lu2Mg2Al2Si2O12 (LMAS) host. The co-doping strategy proposed in this research significantly improves the pressure response range of the phosphors, and the decay degree of the overall integral intensity and the fluorescence intensity ratio (FIR) were first proposed to be used for pressure sensing. Therefore, multi-mode optical pressure sensing can be realized with the use of the LMAS:Eu2+,Mn2+ phosphor.

Summary: In this study, we investigated the optical and structural responses of a one-dimensional metal halide (HMTA)(3)Pb2Br7 under pressure. We found that applying mild pressure (<0.6 GPa) resulted in enhanced broadband emission and prolonged carrier lifetime. Additionally, the band gap narrowed with pressure due to enhanced orbital coupling between the metal and halogen. Our high-pressure studies not only reveal the regulation mechanism of self-trapped exciton (STE) emission in one-dimensional metal halides, but also highlight the potential of pressure treatment as a powerful strategy to tune the emission of white-light materials.

Summary: The wide application of excimer materials in the OLED field is mainly driven by the regulation of their stacking structure. This study designed three anthracene derivative molecules with sterically hindered substituents and prepared crystals with different aggregating structures to investigate the relationship between their structures and properties. The study found that under high pressures, these anthracene groups exhibit enhanced fluorescence during the formation of excimers, while the ones that have already formed excimers under ambient conditions show a wider red-shift range. The piezochromic fluorescence behavior observed indicates that regulating the aggregation mode of anthracene groups can meet different application requirements and guide the expansion of excimer materials' usage.

Summary: The pressure-dependent luminescence behavior of purely organic compounds is an important topic in the field of stimulus-responsive smart materials. This study filled in the gap regarding pressure-dependent room-temperature phosphorescence (RTP) of purely organic compounds by investigating the model molecule selenanthrene (SeAN) with a folded geometry. It discovered a unique phenomenon of pressure-induced RTP enhancement in an SeAN crystal, along with an underlying mechanism involving folding-induced spin-orbit coupling enhancement. In addition, pressure-induced RTP enhancement was observed in an analog of SeAN, which exhibited white-light emission.

Summary: High-pressure chemistry plays a significant role in the development of the scientific community. Pressure-induced emission (PIE) in halide perovskites is increasingly recognized for its potential applications in pressure sensing and optoelectronic devices. The importance of PIE and PIE retention in scintillators and solid-state lighting is highlighted for designing high-performance optoelectronic materials. PIE materials not only show promise in scintillator and lighting applications, but also have potential in display imaging and anti-counterfeiting.
