Summary: In this study, nickel-doped carbon dots (Ni-CDs) with tunable fluorescence emission were successfully synthesized using a simple one-step solvothermal method. The introduction of Ni enhanced the fluorescence intensity and caused a redshift. By mixing Ni-CDs with polyvinylpyrrolidone (PVP), the self-quenching effect of solid-state fluorescence was effectively avoided. Based on this, high-performance green, yellow, and red light-emitting diodes (LEDs) were constructed, demonstrating the potential of these carbon dots for solid-state lighting applications.

Summary: In recent years, there has been considerable interest in nonconjugated organic luminophores, which provide a new conceptual basis for alternative photoluminescence-based technologies. This study utilized the polymerization of 3,4-dihydropyran to prepare nonconjugated photoluminescent polymer nanoparticles. The remarkable feature of this material is its excitation-dependent multicoloremission, ranging from blue to yellow, which is attributed to the presence of independent, non-interacting chromophores on the polymer structure. The removal of unsaturated structures furthermore enhances the photoluminescence quantum yield (QY) of the polymer up to 0.20 (lambda(ex) = 355 nm). This work introduces a new type of nonconjugated organic luminophore with high QY and multicoloremission.

Summary: Research on multiemission fluorescent carbon dots excited at one wavelength has shown great promise due to their label-free property, easy synthesis, multicolor visualization, and ability to prevent background interference. A new template strategy using fluorescent precursors has been developed for the synthesis of multiemission carbon dots (M-CDs), which show three different emissions attributed to solvent, surface defect, and precursor luminophores. The M-CDs can meet optical requirements by adjusting the amount of NaOH or solvothermal synthesis time, demonstrating better capabilities than previously reported M-CDs. Additionally, a multicolor sensor using M-CDs and rhodamine B has been successfully utilized for cell imaging, showing a color evolution from dark blue to orange based on the pH value of the medium.

Summary: Photodynamic therapy (PDT) based on the generation of reactive oxygen species (ROS) has gained attention in tumor treatment. However, the hypoxic tumor microenvironment inhibits ROS generation and high glutathione levels neutralize ROS, reducing the effectiveness of PDT. This study constructs porphyrinic metal-organic framework PCN-224 and decorates it with gold nanoparticles (PCN-224@Au) to enhance ROS generation and deplete glutathione, amplifying damage to cancer cells. In vitro and in vivo experiments demonstrate that PCN-224@Au can serve as an oxidative stress amplifier for enhanced PDT, providing a promising solution for addressing intratumor hypoxia and high GSH levels.

Summary: Photodynamic therapy (PDT) is an emerging treatment method that has attracted interest due to its non-invasiveness, repeatable treatment, high spatiotemporal resolution, and few side effects. However, the short lifespan and diffusion distance of reactive oxygen species in tumor cells seriously limit the therapeutic efficacy of PDT. Therefore, the design and preparation of photosensitizers targeting specific subcellular organelles can significantly improve the efficacy of PDT.
