Summary: A trigonal luminescent metallacage with excellent Aggregation-Induced Emission (AIE) properties was constructed by coordination-driven self-assembly. An efficient artificial light-harvesting system was successfully constructed by selecting the metallacage as the donor and Nile Red (NiR) as the acceptor molecule, achieving energy transfer.

Summary: The potential of using metallic structures with photonic singularities for harvesting light has been demonstrated in nanophotonics, sensing, and bio-medical applications. A new method for achieving massive photonic singularities for spatially modulated light harvesting is proposed. The method allows for localized light confinement at spatially distributed singularities.

Summary: In this study, through-space donor-alkyl bridge-acceptor luminogens were developed as new organic single-molecule white light emitters. The white light emission was achieved through multiple higher lying singlet and triplet states, and exhibited characteristics of delayed fluorescence and phosphorescence color mixing. Crystal structure analysis revealed that the alkyl chain length greatly influenced the solid-state optical properties. Additionally, the microrod crystals of these emitters demonstrated waveguiding abilities to propagate phosphorescence.

Summary: Multicolor fluorescent carbon dots (CDs) with red, yellow, and blue emissions were prepared using aromatic precursors with different amounts of benzene rings through solvothermal method. The prepared CDs had spherical shape, small size (<10 nm), rich surface functional groups, and good stability. By mixing the CDs with PVA matrix, transparent and flexible films were produced and LEDs with bright blue, yellow, and red light were successfully manufactured. The synthesized CDs show potential application in multi-color monitors as a promising candidate for LEDs.

Summary: A highly emissive microgel with temperature responsive fluorescence emission was synthesized, and a novel artificial light harvesting system with high energy transfer efficiency was constructed by inserting Rhodamine B onto the microgels surface. Both the microgel and light-harvesting system showed good cytocompatibility, making them ideal candidates for cell imaging. This provides a new strategy for tunable luminescent nanomaterials fabrication and expands potential applications in fields such as stomach recognition, temperature sensors, and drug delivery.

Summary: Despite recent progress, highly efficient solution-processable pure red thermally activated delayed fluorescence (TADF) emitters are rare. To address this issue, a novel TADF emitter, tBuTPA-CNQx, was designed and synthesized, which exhibited a small singlet-triplet energy gap, high photoluminescence quantum yield, and short delayed fluorescence lifetime. The use of specific building blocks improved solubility and minimized intermolecular interaction. The resulting OLED achieved high external quantum efficiency and pure red emission peak, making it one of the highest performing pure red TADF OLEDs reported to date.

Summary: Researchers have successfully developed high-performance narrowband red organic light-emitting diodes (OLEDs) using boron-dipyrromethene (BODIPY) skeleton in combination with a methyl-shield strategy. These emitters exhibit small full-width at half-maxima (FWHM) ranging from 21 nm (0.068 eV) to 25 nm (0.081 eV) and high photoluminescence quantum yields (φ(PL)) ranging from 88.5% to 99.0% in toluene solution. High-performance narrowband red OLEDs with external quantum efficiency as high as 18.3% at 623 nm and 21.1% at 604 nm have been achieved using these emitters as luminescent materials, representing the first successful case of achieving NTSC pure-red OLEDs with the Commission Internationale de l'eclairage (CIE) coordinates of [0.67, 0.33] based on conventional fluorescent emitters.

Summary: By changing the central porphyrin core to a phthalocyanine core in macromolecular structures, new dendrimers with multiple conjugated endgroups were prepared and studied. Efficient energy transfer from peripheral units to central unit led to intense red light emission and oxygen photosensitization, while significantly boosting two-photon absorption cross-sections. The impact of this structural change was discussed in relation to dendrimer generations using DFT and molecular dynamic calculations.

Summary: In this study, a low-metal iron-supported catalyst (Fe20/NC-Mg) was reported for the efficient synthesis of quinoxaline compounds, using water as a solvent and without additional bases. The synergistic effect of FeNx site and Mg (OH)2 nanorods in the catalyst played a key role in achieving high yields (82-91%) in 16 examples. The gram-level synthesis and reusability of the catalysts after four cycles demonstrated its industrial application potential.
