Summary: Here, a facile and selective synthesis of cationic azatriphenylene derivatives was achieved through electrochemical intramolecular cyclization, where the key step involves atom-economical C-H pyridination without a transition-metal catalyst or an oxidant. This proposed strategy provides a practical approach for introducing cationic nitrogen (N (+)) into pi-electron systems, thus expanding the molecular design of N (+)-doped polycyclic aromatic hydrocarbons.

Summary: In this study, CeO2-based porous carbonaceous frameworks (CeO2 PCFs) were used as antioxidant nanozymes to scavenge reactive oxygen species and absorb benzo[a]pyrene. CeO2 PCFs exhibited excellent superoxide dismutase-like and catalase-like activity, effectively eliminating superoxide radical, hydroxyl radical, and hydrogen peroxide. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) free radical scavenging assay confirmed the free radical scavenging ability of CeO2 PCFs. Furthermore, CeO2 PCFs with large surface area and porous structure efficiently adsorbed benzo[a]pyrene. The designed CeO2 PCFs can serve as new antioxidant nanozymes for scavenging reactive oxygen species and adsorbing polycyclic aromatic hydrocarbons (PAHs).

Summary: Tidal action significantly affects the release of PAHs from estuarine sediments to seawater. The release is 2.0-3.5 times higher compared to no tidal action. PAHs concentration shows a positive correlation with suspended substance content. Increased seawater depth intensifies tidal action and leads to more PAHs release, especially dissolved PAHs. Sediments play a crucial role in the fate of PAHs and act as major sinks in the sediment-seawater system.

Summary: In this study, interpretable deep learning was used to identify the structure-property relationships of polybenzenoid hydrocarbons (PBHs) using a ring-based graph representation. The results showed agreement with conventional organic chemistry knowledge and electronic structure-based analyses, while also revealing new behaviors and influential structural motifs. The effects of linear, angular, and branching motifs on molecular properties were evaluated and compared, and the role of dispersion in mitigating torsional strain in nonplanar PBHs was explored. These findings contribute to a deeper understanding of PBH behavior and provide a foundation for designing new functional PBHs.

Summary: At elevated temperatures, a strained, cyclic meta-quaterphenylene acetylene undergoes an intramolecular cyclization reaction to form benz[e]indeno[1,2,3-hi]acephenanthrylene. This reaction represents a Diels-Alder reaction at the 2-, 1-, 1 '-, and 2 '-positions of a biphenyl derivative, similar to the bay regions of perylene and other periacenes. Kinetics studies reveal that the reaction has a similar energy barrier to a concerted [4 + 2]-cycloaddition.

Summary: Nanographene materials, particularly bottom-up synthesized graphene quantum dots, hold great potential as single quantum emitters. The solubility of the starting materials is a key parameter for efficient purification and to fully exploit their properties. Highly soluble and easily processable rod-shaped graphene quantum dots with high fluorescence quantum yields up to 94% were synthesized, allowing for accurate description of their photophysical properties. The use and characterization of graphene quantum dots is limited by their tendency to form aggregates, but the authors successfully synthesized individualized rod-shaped nanographenes with up to 132 sp(2) carbon atoms, enabling precise description of their intrinsic photophysical properties.

Summary: Copious use of antibiotics in aquaculture farming systems has led to contamination of surface water in certain countries. Our goal was to develop a slow-release oxidant that could be used on-site to decrease antibiotic concentrations in discharges from aquaculture lagoons. We achieved this by creating a slow-release permanganate (SR-MnO4-) composed of a biodegradable wax and a phosphate-based dispersing agent. Kinetic experiments confirmed the first-order reaction between antibiotic and MnO4-, with second-order rates ranging from 0.056 to 0.128 s(-1) M-1. Batch experiments indicated that solution pH, water matrices, and humic acids affected the degradation efficiency of sulfadimethoxine (SDM). A mixture of KMnO4/beeswax/paraffin (SRB) at a ratio of 11.5:4:1 (w/w) demonstrated better biodegradability and continual release of MnO4-, although MnO2 formation altered release patterns. The addition of tetrapotassium pyrophosphate (TKPP) delayed MnO2 aggregation and increased SDM removal efficiency to 90%. The release data of MnO4- fit the Siepmann-Peppas model in the long term (t < 48 d), while the Higuchi model provided a better fit for shorter timeframes (t < 8 d). Our flow-through discharge tank system, using SRB with TKPP, consistently reduced SDM concentration in both DI water and lagoon wastewater. These findings support the effectiveness of SRB with TKPP as a composite for treating antibiotic residues in aquaculture discharge water.
