Summary: Lanthanide-doped metal-organic frameworks (Ln-MOFs) with upconversion luminescence were successfully synthesized by doping Yb-BTC MOF 1D microrods with Er3+, Ho3+, Tb3+, and Eu3+ ions. The MOFs exhibited both cooperative luminescence from Yb3+ and characteristic emission bands of the dopant ions. In contrast, the MOFs doped with Tm3+, Pr3+, Sm3+, and Dy3+ ions only showed the 497 nm upconversion emission band from Yb3+.

Summary: The luminescence properties of two series of lanthanide-containing metal-organic frameworks were studied, showing characteristic emissions of Nd(III), Eu(III), and Tb(III) in different compounds. The color of emission in mixed-lanthanide complexes can be fine-tuned depending on the relative amount of Eu(III) and Tb(III). A small amount of Eu(III) is sufficient for observing the most intense Eu(III) transitions.

Summary: Lanthanide metal-organic frameworks (Ln-MOFs) with adjustable structures and wide optical applications are highly studied. However, MOFs with stable framework structures and wide linear pH response in acidic or alkaline solutions are rare. In this study, a new metal-organic framework material was synthesized using 4,4',4''-s-triazine-2,4,6-triyltribenzoate as the organic ligand coordinated with lanthanide ions. The material exhibited a porous three-dimensional square framework structure and emitted red or green fluorescence under 365 nm UV light. The framework showed wide linear pH response (pH=0-14) and could be a potential fluorescence sensing material for pH detection.

Summary: Defect engineering has been widely observed and applied in crystal materials, but the relationship between defect formation and crystallization process needs to be clarified, and defect healing presents a significant challenge. Utilizing a new coordination complex (HNU-53), crystal defects were created by increasing reaction time and crystal size. This led to the simultaneous generation of crystal color centers during crystal growth, resulting in fluorescence quenching. By introducing rare earth ions and controlling crystal growth through coordination competition, the crystal defects were reduced and the recovery of fluorescence emission was achieved.

Summary: Immunotherapy is a promising treatment strategy for tumor regression, but it has low response rates due to the lack of immunogenicity in tumor cells. This study presents a strategy to enhance the immunogenicity of tumor cells by inducing cascade immunogenic tumor ferroptosis. A nanoplatform was developed to trigger lipid peroxidation and activate ACSL4, resulting in irreversible cascade immunogenic ferroptosis. This approach could overcome the limitations of current immunotherapy.

Summary: Hydrogenolysis is an effective method for converting polyolefins into high-value chemicals. In this study, the activity of CeO2-supported Ru single atoms, nanoclusters, and nanoparticles in LDPE hydrogenolysis showed a volcanic trend. Metal-support interactions and hydrogen spillover effect were identified as the two key factors in the reaction. Only when the balance between these two effects is achieved, as in CeO2-supported Ru nanoclusters, can the hydrogenolysis activity be promoted.
