Electroreduction of carbon dioxide (CO2) or monoxide (CO) toward C2+ hydrocarbons such as ethylene, ethanol, acetate and propanol represents a promising approach carbon-negative electrosynthesis chemicals. Fundamental understanding the carbon─carbon (C-C) coupling mechanisms in these electrocatalytic processes is key to design development electrochemical systems at high energy conversion efficiencies. Here, we report investigation CO electreduction on single-atom copper (Cu)...
The development of high mobility emissive organic semiconductors is great significance for the fabrication miniaturized optoelectronic devices, such as light emitting transistors. However, challenge exists in designing key materials, especially those who integrates triplet exciton utilization ability. Herein, dinaphthylanthracene diimides (DNADIs), with 2,6-extended anthracene donor, and 3'- or 4'-substituted naphthalene monoimide acceptors were designed synthesized. By introducing...
Herein, we report an electrochemical protocol for the dicarboxylation of aryl alkynes using CO2. With a graphite rod as cathode and Al sacrificial anode, series valuable butenedioic acids are obtained in moderate to excellent yields with E/Z ratio up 50:1. This method features high E-selectivity, step atom economy, easy scalability, nice substrate scope, which renders it appealing promising applications organic synthesis materials chemistry.

Abstract Efficient electrochemical CO 2 reduction reaction (ECO RR) to multi‐electron reductive products remains a great challenge. Herein, molecular engineering of copper phthalocyanines (CuPc) was explored by modifying electron‐withdrawing groups (EWGs) (cyano, sulfonate anion) and electron‐donating (EDGs) (methoxy, amino) CuPc, then supporting onto carbon paper or cloth means droplet coating, loading with nanotubes coating in polypyrrole (PPy). The results showed that the PPy‐coated CuPc...
Metal–organic frameworks (MOFs) are used in catalysis due to their high specific surface area and porous structure. The dispersed active sites limited reaction space that render MOFs have the potential for highly selective electrocatalytic CO2 reduction (ECO2RR).
