Summary: The peroxidase-like activity of CdV2O6 nanorods has been greatly improved through modification with N, N-dicarboxymethyl perylene-diimide (PDI) as a photosensitizer. The colorless chromogenic substrate 3,3', 5,5'-tetramethylbenzidine (TMB) is used to evaluate the peroxidase-like behaviors, which rapidly changes into blue oxTMB in the presence of H2O2 in just 90 s. PDI-CdV2O6 exhibits high stability at elevated temperatures and retains more than 70% of its catalytic activity over a wide temperature range of 15 to 60 degrees C.

Summary: A cationic perylene probe was synthesized for sensitive determination of tartrazine. The probe exhibited excellent sensing performance, with detection and quantification limits as low as 2.42 and 8.07 nmol L-1, respectively. The high binding affinity between the probe and tartrazine allowed for great anti-interference capacity. Additionally, the approach was successfully visualized using portable devices and applied to monitor tartrazine in various food condiments.

Summary: The SAPDI/Bi4O7 composites, prepared by modifying Bi4O7 with self-assembled perylene diimide (SAPDI), showed accelerated transfer of photogenerated electrons due to the synergistic interaction between Bi4O7 and SAPDI. The modified Bi4O7 effectively degraded Rhodamine B (RhB), methyl orange (MO), and methylene blue (MB) dyes, especially RhB, with a degradation rate 51.5 times higher than that of pure Bi4O7. After four recycling experiments, the degradation performance remained at 80%, indicating good stability of the catalyst. Superoxide radicals (center dot O-2(-)) were found to be the main active species in the photocatalytic process, and the photoinduced charge transfer mechanism belonged to type II based on the electronic band structure.

Summary: The research on perylene diimide (PDI) aggregates has effectively promoted their applications in organic photovoltaic solar cells and fluorescent sensors. In this study, a PDI trimer with different absorption and fluorescence properties in the presence of water in the mixed solvent of THF is investigated. The results show that the hydrophobicity of PDI trimer plays a crucial role in its aggregate properties and provides guidance for the design of PDI-based organic photovoltaic solar cells.

Summary: The organic-inorganic PDI/Bi2O4 composite photocatalyst prepared in this paper showed a higher reaction rate and cycling stability. The close interface contact between the PDI nanorods and Bi2O4 nanorods was found to accelerate the migration rate of photogenerated carriers, resulting in enhanced photocatalytic performance. The speculated type II photocatalytic mechanism was proposed based on the electronic band structure of PDI and Bi2O4.

Summary: Well-dispersed Pt quantum dots were successfully deposited onto a PDI supramolecular nanorods surface, forming Pt QDs/PDI composites with excellent photocatalytic properties in the degradation of phenol. The enhanced photocatalytic performance can be attributed to the efficient trapping and transporting of electrons by Pt QDs, which also act as active sites during the photocatalytic reaction, leading to high stability and utilization in water environmental purification.

Summary: The development of an all-organic Z-scheme heterojunction photocatalyst with matched band structure, efficient electron transfer, and excellent photocatalytic performance is important for a sustainable future. A novel perylene diimide/phthalocyanine iron (PDI/FePc) heterojunction with strong pi-pi interaction was synthesized, showing strong visible-light-driven photocatalytic degradation activities for tetracycline hydrochloride (TC). The TC removal rate of PDI/FePc was three times and 87.5 times higher than that of PDI and FePc, respectively. The strong pi-pi interactions between PDI and FePc reduced the layer spacing of the supramolecular structure, facilitating the separation and transfer of photogenerated carriers in the built-in electric field.

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.
