Facile preparation of microporous conjugated polycarbazoles via carbazole-based oxidative coupling polymerization is reported. The process to form the polymer network has cost-effective advantages such as using a cheap catalyst, mild reaction conditions, and requiring single monomer. Because no other functional groups halo groups, boric acid, alkyne are required for polymerization, properties derived from monomers likely be fully retained structures final polymers easier characterize. A...
The hydrogen evolution reaction (HER) through electrocatalysis is promising for the production of clean fuel. However, designing structure catalysts, controlling their electronic properties, and manipulating catalytic sites are a significant challenge in this field.
