We use a perylene diimide (PDI) derivative as the third component to prepare high-efficiency ternary organic solar cells (OSCs). PDI derivatives usually bear a wide bandgap and a long exciton diffusion length, which will be helpful to promote the device efficiency and still remain a high open-circuit ( V oc ) value. Compared with the binary OSC, the photovoltaic performance simultaneously improved

The synthesis of diarylamine is extremely important in organic chemistry. Herein, we report a novel electrochemical reductive arylation of nitroarenes with arylboronic acids. A variety of diarylamines have been synthesized without the need for transition-metal catalysts. The reaction can be scaled up efficiently in a flow cell and several derivatization reactions were carried out smoothly. CV experiments

A large fraction of energy, including solar energy, is dissipated into ambient atmosphere as low-grade waste heat. Efficient utilization of such energy is critical to address current energy crisis and global warming issue. Herein, we report the efficient NIR-photothermal, thermoelectric and thus photo-thermo-electric conversion of polyoxovanadate compound ([Ni(1,10-phenanthroline)3][V14O34Cl]Cl, NiV14)

Since the successful preparation of few-layer transition metal carbides from three-dimensional MAX phases in 2011, MXenes (known as a family of layered transition metal carbides, nitrides and carbonitrides) have been intensively studied. Though MXenes have been adopted as active materials in many applications, issues including aggregation and restacking are likely to hamper their potential applications

Crystalline covalent organic frameworks (COFs) are a new class of porous polymeric semiconductors with network topologies, which are built from the integration of selected organic blocks via covalent bond linkage.

We report on a combined experimental and theoretical study of the wetting and reactivity of water-lean carbon capture solvents on the surface of common column packing materials. Paradoxically, we find that these solvents are equally able to wet hydrophobic and hydrophilic surfaces. The solvents are amphiphilic and are able to adapt to any interfacial environment due to their inherent heterogeneous

Efforts to selectively convert polypropylene (ca. 30% of all plastic waste) have not been particularly successful. Typical distributions span from gas to solid products, highlighting a challenging cleavage control. We design carbon-supported platinum nanoparticles for complete hydrocracking into liquid hydrocarbons (C5–C45). The metal and carrier phases operate synergistically. The cleavage activity
