摘要:共轭微孔聚合物(cmps)由于其结构可设计性和功能多功能性,已成为有前途的有机转化多相光催化剂.然而,受光生激子分离不充分的限制,其光催化效率远低于预期.在此,我们展示了一种氰化策略,通过选择性地将咔唑和氰基分别作为供电子和吸电子单元来促进 Cmp 中的电荷载流子分离.由此产生的 Cmp 具有 π 扩展的供体 (D)-受体 (A) 共轭结构,赋予它们独特的半导体特性,其中促进了有效的电荷分离和转移以及广泛的可见光吸收.与无氰对应物相比,氰基官能化的 Cmp 显示出优异的光催化效率,例如氯化物的光催化还原脱卤.更突出的是,所设计的 Cmp 的完全可回收性以及至少 10 次运行的催化活性而不会损失在氯化物的光催化还原脱卤中的催化性能,这证明了它们的稳健性和可持续性.

摘要:The present invention provides a method for the continuous synthesis of a substituted benzoic-acid organic substance. The continuous synthesis method comprises: in the presence of catalyst and organic solvent, the organic matter represented by formula (I) and oxygen are continuously inputted to a continuous reaction apparatus for continuous oxidation reaction to obtain a substituted benzoic-acid organic substance, which is discharged continuously, the substituted benzoic-acid organic substance having the structure represented by formula (II). Oxygen is a green reagent and is inexpensive and readily available; a large amount of wastewater, waste gas, and solid waste is not generated after the reaction, and the system is easy to handle. The use of a continuous reaction operation can reduce the risk of flash distillation and explosion of solvent due to a high concentration of oxygen in a batch reaction. Under the same oxidation conditions, the continuous preparation process can reduce the escape of oxygen, greatly increasing the oxygen utilization rate and also simplifying the operation, improving the safety of the reaction and the yield of the substituted benzoic-acid organic substance.
