Background: Perylene diimide (PDI) is among the most investigated non-fullerene electron acceptor for organic solar cells (OSCs). Constructing PDI derivatives into three-dimensional propeller-like molecular structures is not only one of the viable routes to suppress the over aggregation tendency of the PDI chromophores, but also raises possibilities to tune and optimize the optoelectronic property of the molecules. Objective: In this work, we reported the design, synthesis, and characterization of three electron-accepting materials, namely BOZ-PDI, BTZ-PDI, and BIZ-PDI, each with three PDI arms linked to benzotrioxazole, benzotrithiazole, and benzotriimidazole based center cores, respectively. Method: The introduction of electron-withdrawing center cores with heteroatoms does not significantly complicate the synthesis of the acceptor molecules but drastically influences the energy levels of the propeller-like PDI derivatives. Result: The highest power conversion efficiency was obtained with benzoxazole-based BOZ-PDI reaching 7.70% for its higher photon absorption and charge transport ability. Conclusion: This work explores the utilization of electron-withdrawing cores with heteroatoms in the propeller-like PDI derivatives, which provides a handy tool to construct high-performance non-fullerene acceptor materials.

A novel post-denitrification system fed by carbon source from primary sludge (PS) was used for enhancing biological nitrogen removal (BNR) of low C/N wastewater. This system included one anoxic/oxic (AO) reactor and a special reactor for simultaneous sludge fermentation and denitrification (Sifeden). Ammonia was nitrified to nitrate in AO and then the nitrate was reduced to dinitrogen in Sifeden , into which PS was added intermittently. Results showed that this system had high performance on nitrogen removal. Total nitrogen (TN) removal efficiency was higher than 85% and the effluent TN≤10mg/L in the condition of influent C/N≤2. In Sifeden, volatile fatty acid (VFA) produced from PS fermentation provided electron donor for nitrate reduction, and PS was preliminarily stabilized simultaneously. Oxidation-Reduction Potential (ORP) had a significant correlation with the denitrification performance. TN removal efficiency could be further improved if adopting proper PS addition strategy according to the ORP profiles.

Power And Energy

Pseudocapacitive polymers offer potential for higher energy densities than electrostatic double layer capacitive materials and lower cost than pseudocapacitive metal oxides. These polymers typically demonstrate good stability when storing positive charge but poor stability when storing negative charge. The power and energy densities of these materials is also limited when the operating voltage window is restricted to positive voltages. The development of polymers capable of stable positive and negative charge storage is necessary to allow a wider voltage window and create high performance polymer supercapacitors. Here we present a PEDOT-pendant tetrachlorinated perylene diimide polymer capable of storing positive and negative charge, which utilizes a donor-nodeacceptor architecture to prevent electronic interaction between positive and negative charge storing units. The polymer films show balanced charge storage and excellent stability in both positive and negative charge storage, retaining more than 80% of their capacitance over 1000 cycles. The films demonstrate moderate capacitances of 78.6 F g<sup>-1</sup> in the positive region and 73.1 F g<sup>-1</sup> in the negative region at 0.5 A g<sup>-1</sup>, as well as excellent rate capabilities in positive and negative charge storage regions of 87% and 56% at 20 A g<sup>-1</sup>, respectively. The polymer film was applied as both electrodes in a symmetric type III supercapacitor device with a gel polymer electrolyte, demonstrating a wide operating potential range of 2.2 V. These results demonstrate that the cycling stability of ambipolar polymers can be improved using a donor-node-acceptor polymer architecture with an extended π-conjugated donor unit. <br>
