Additive assisted strategies play a crucial role in optimizing the morphology and improving the performance of organic solar cells (OSCs), yet the molecular-level mechanisms remain unclear. Here, we employ molecular dynamics (AIMD) and density functional theory (DFT) to elucidate the influence of typical additives of 1,8-diiodooctane (DIO) and 3,5-dichlorobromobenzene (DCBB) on molecular packing, electronic structures, and charge transport. It can be observed that both additives can enhance the stacking properties of the donor and acceptor materials, yet they have different effects on the local electrostatic environment.

Innate immunity is crucial in orchestrating the brain immune response, however, glioblastoma multiforme (GBM) has evolved sophisticated mechanisms to evade innate immune surveillance, posing significant challenges for current immunotherapies. Here, a therapeutic strategy is reported that aims at reactivating innate immune responses in GBM via targeted induction of mitochondrial stress, thereby enhancing tumor immunogenicity. Specifically, innate immune-stimulating nanoparticles (INSTNA) are developed, encapsulating positively charged iridium-based complexes (Ir-mito) and small interfering RNA against Methylation-Controlled J protein (si-MCJ) to attenuate mitochondrial respiration.

College of Polymer Science and Engineering, State Key Laboratory of Advanced Polymer Materials, Sichuan University, Chengdu, 610065, P.R. China.

Simultaneous promotion of charge and mass transportation between catalytic centers and reactants is crucial for photocatalysis but remains a substantial challenge on account of the widespread use of homogeneous or heterogeneous photocatalysts that suffer from sluggish reactant-diffusion kinetics or interfacial electron-transport resistance, respectively. Herein, we demonstrate the construction of conjugated microporous polymer aerogels as available quasi-homogeneous photocatalysts by integrating structural designability, which allows for the incorporation of electron-acceptor building blocks featuring ultralong-lived excitons as high-concentration local catalytic centers, and hierarchically porous gel networks that wrap solvent and reactants to provide a "single" reaction phase without interfacial resistance. A total of 18 samples of C─H functionalization reactions underpinned by four different mechanisms were screened to showcase the general applicability of the obtained aerogel photocatalysts, which achieved remarkable conversion efficiencies, gram-scale productivities, and recyclability.
