Summary: In recent years, there has been increasing effort to develop single-phase white phosphors for white light-emitting diodes (WLEDs) due to limitations of traditional WLEDs such as reabsorption and color deviation. A new strategy using the Bi3+-Eu3+ energy transfer in suitable single-phase phosphors has been proposed. In this study, Gd3TaO7:xBi(3+) and Gd3TaO7:0.01Bi(3+),yEu(3+) phosphors were synthesized and characterized. The results show the potential of Gd3TaO7:0.01Bi(3+),yEu(3+) phosphor as a viable candidate for WLED applications.

Summary: The photophysical and optoelectronic characteristics of ternary lanthanide (Eu, Sm) complexes with diacetylmethane (DAM) and substituted 2,2'-bipyridine derivatives as auxiliary ligands were thoroughly examined. The complexes exhibited conducting properties as suggested by optical and electronic band gap analyses. Vibrational spectral analysis confirmed the coordination of lanthanide ions with oxygen and nitrogen atoms of DAM and the heteroaromatic auxiliary ligand respectively. The prepared trivalent complexes emitted red light, which was further validated by Commission Internationale de l' Eclairage (CIE) color coordinates, indicating their luminous nature. These red light emitting materials are of significant importance in solid state electronics, flat panel displays, and organic light emitting devices (OLEDs).

Summary: In this study, we investigated the photoluminescence emission properties of Eu3+ doped CaAl2O4 in the presence of Li+, Mg2+, and Bi3+ ions. It was found that the 0.01Eu3+:CaAl2O4 phosphor emits intense red emission at 616 nm when excited with 393 nm (Eu3+ line) and 262 nm (charge transfer band). The emission intensity is significantly enhanced in the presence of Li+ doping, while it is decreased with Bi3+ doping. Moreover, the 0.01Eu3+:CaAl2O4 phosphor exhibits highly pure red color in the warm light region.

Summary: This study investigates the mechanism of photoinduced phase segregation (PPS) in mixed-halide perovskite microplatelets. The research finds that under continuous irradiation, the heterogeneous microplatelets exhibit PPS while the homogeneous microplatelets only show slight photoluminescence dimming. The study also reveals the correlation between PPS and structural heterogeneity and proposes a mechanism of localized electric field-induced drift of halide ions/carriers.

Summary: A visible light photosensitizing metal-organic cage is used as an artificial supramolecular reactor to control the reaction of aryl radicals with terminal olefins, resulting in the selective transformation of geometrically defined E/Z-alkenes. The hydrophobic cage efficiently includes aromatic substrates, promoting Meerwein arylation and protecting E-isomeric products, while benzonitrile induces efficient E -> Z isomerization. In addition to pi-pi stacking, hydrogen bonding and halogen bonding interactions play a role in controlling the arylation of aliphatic terminal olefins. This switchable cage-confined arylation catalysis has been demonstrated in the syntheses of Tapinarof and a marine natural product, achieving controllable E/Z selectivity.

Summary: The host-guest interaction and microenvironment around the Re complex in two metal-organic frameworks, ZIF-8 and UiO-66, were investigated. It was found that ZIF-8 provided a confined space for Re through electrostatic interaction, while UiO-66 offered a relaxed space through coordination interaction. The Re@ZIF-8 exhibited a significantly higher turnover number for CO2 photoreduction compared to Re@UiO-66, which was attributed to the promotion of electron transfer in Re@ZIF-8 and hindrance in Re@UiO-66. The spatial confinement in Re@ZIF-8 stabilized charged intermediate species during CO2 activation, whereas Re-triethanolamine adducts prevailed in Re@UiO-66 due to the accessibility of the Re complex. This study demonstrates the feasibility of altering CO2 activation pathway through the microenvironment of a molecular catalyst in artificial photosynthesis.

Summary: Simultaneous removal of ethane and acetylene from a C2-gases mixture for ethylene purification is challenging due to their similar properties. Multifunctional metal-organic frameworks (MOFs) were constructed via dynamic spacer installation (DSI) to optimize the pore-nanospaces for efficient C2H4 isolation. The optimized MOF showed four times higher adsorption capacities for ethane and acetylene than the prototype. This study demonstrates a promising protocol for screening MOFs through porenanospace engineering for challenging separations.

The effectiveness of chloroform extraction by [Zn(4-pmntd)(opa)] was confirmed through various methods. A filtration film created using natural rubber successfully separated chloroform from water with high purity. Therefore, [Zn(4-pmntd)(opa)] has significant potential for low-energy separation and recycling of chloroform from water under ambient conditions.

Summary: In this study, In2O3@Ni2P (IO@NP) heterojunctions were successfully achieved by annealing MIL-68(In) and combining it with NP via a simple hydrothermal method. Visible-light photocatalysis experiments demonstrated that the optimized IO@NP heterojunction exhibited a dramatically improved H(2) release rate of 2485.5 μmol g(-1) h(-1), 92.4 times higher than that of IO. Optical characterization revealed that the doping of IO with an NP component promoted the rapid separation of photo-induced carriers and enabled the capture of visible light. Moreover, the interfacial effects of the IO@NP heterojunction and synergistic interaction between IO and NP provided plentiful active centers for reactants.

Summary: Photocatalytic reduction of excess CO2 in the atmosphere to value-added chemicals by visible light can be achieved using a trinuclear Re(I)-coordinated organic cage (Re-C-4(R)) as the supramolecular photocatalyst. The Re-C-4(R) exhibits higher catalytic activity and CO2 adsorption ability compared to its mononuclear analogue Re-bpy, due to its covalent linkage, cryptand structure, and multiple amine groups. The trinuclear cryptate structure of Re-C-4(R) also facilitates electron transfer efficiency during CO2 reduction, as indicated by its shorter decay lifetimes in transient absorption and photoluminescence decay spectra compared to Re-bpy.

Summary: In this study, N-heterocyclic vinyl (NHV) substituted diphosphenes were isolated and characterized as both E- and Z-isomers. The thermodynamically more stable E-2b undergoes reversible photo-stimulated isomerization to Z-2b, which can be thermally reverted back to E-2b. The study also reveals the coordination of both E- and Z-2b to an AuCl fragment, as well as their different cycloaddition reactions.
