Summary: A new luminescent probe Ru-impa based on a ruthenium complex has been synthesized and characterized, showing rapid and selective detection of Cu2+ and pH in a wide pH range. The probe exhibits low detection limits and can detect Cu2+ in drinking water below the regulated limit. It can also monitor Cu2+ level fluctuation in cells and function as a pH sensor under extremely alkaline conditions.

Summary: This paper presents flexible pressure sensors based on 3D printing technology, with a sandwich structure design and a hollow prism structure pressure sensitive layer. Experimental synthesis of three kinds of flexible composite dielectrics demonstrated that the sensor with PDMS doping both BaTiO3 and CNTs showed the highest sensitivity, 1.3 times that of the reference sensor, indicating that fabricating composite dielectrics in this way has the potential to improve device performance.

Summary: A new ruthenium complex with 5-aminosalicylic acid as the ligand was synthesized, characterized, and structurally analyzed. Density functional theory calculations were used to determine important molecular orbital parameters, which were consistent with experimental results. Luminescence analysis showed that the complex is a suitable candidate for photoluminescent material based on its emission properties.

Summary: In this study, a luminescence probe called Ru-COU was developed, which combined tris(bipyridine)ruthenium(II) complex with a coumarin derivative through a formaldehyde-responsive linker. The probe showed a large emission shift (>100 nm) and good water solubility, achieving ratiometric emission responses at 505 nm and 610 nm towards formaldehyde under acidic conditions. Ratiometric luminescence imaging of formaldehyde in living cells and Alzheimer disease mouse's brain slices demonstrated the potential value of Ru-COU for the diagnosis and treatment of formaldehyde related diseases.

Summary: Luminescent platinum(II) small molecules have unique properties due to Pt(II)-Pt(II) interaction, while the incorporation of Pt(II) into polymers is still in early stages. In this study, random copolymers were synthesized using ROMP method, showing enhanced Pt(II)-Pt(II) interaction and intense low-energy emissions. The photophysical properties of the polymers were highly dependent on solvents and Pt(II) content, with one polymer successfully demonstrated as a self-referenced luminescent thermometer.
