In 2019,Chemistry of Materials included an article by Meier, Christian B.; Clowes, Rob; Berardo, Enrico; Jelfs, Kim E.; Zwijnenburg, Martijn A.; Sprick, Reiner Sebastian; Cooper, Andrew I.. Recommanded Product: 2,5-Dibromopyridine. The article was titled 《Structurally diverse covalent triazine-based framework materials for photocatalytic hydrogen evolution from water》. The information in the text is summarized as follows:
A structurally diverse family of 39 covalent triazine-based framework materials (CTFs) are synthesized by Suzuki-Miyaura polycondensation and tested as hydrogen evolution photocatalysts using a high-throughput workflow. The two best-performing CTFs are based on benzonitrile and dibenzo[b,d]thiophene sulfone linkers, resp., with catalytic activities that are among the highest for this material class. The activities of the different CTFs are rationalized in terms of four variables: the predicted electron affinity, the predicted ionization potential, the optical gap, and the dispersibility of the CTFs particles in solution, as measured by optical transmittance. The electron affinity and dispersibility in solution are found to be the best predictors of photocatalytic hydrogen evolution activity. The results came from multiple reactions, including the reaction of 2,5-Dibromopyridine(cas: 624-28-2Recommanded Product: 2,5-Dibromopyridine)
2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Recommanded Product: 2,5-Dibromopyridine
