摘要:A Novel 5-Amino-6-Methylquinoline Carboxylic Acid Was Synthesized From 2,3,4-Trifluoro Aniline In 12 Steps And Coupled With Various Types Of Amines To Furnish New Quinolone Antibacterial Agents. Depending On The Structure Of Amine,Some Of Quinolones Showed Comparable Activity To Ciprofloxacin Or Better Gram Positive Activity Than Ciprofloxacin,Demonstrating That The C6 Fluorine Atom Is Not A Necessary Requirement For Good Antibacterial Potency.

摘要:Nature is capable of storing solar energy in chemical bonds via photosynthesis through a series of C—C, C—O and C—N bond-forming reactions starting from CO 2 and light. Direct capture of solar energy for organic synthesis is a promising approach. Lead (Pb)-halide perovskite solar cells reach 24.2% power conversion efficiency, rendering perovskite a unique type material for solar energy capture. We show that photophysical properties of perovskites is useful in photoredox organic synthesis. Because the key aspects of these two applications are both relying on charge separation and transfer. Here we demonstrated that perovskites nanocrystals are exceptional candidates as photocatalysts for fundamental organic reactions, i.e. C—C, C—N and C—O bond-formations. Stability of CsPbBr 3 in organic solvents and ease-of-tuning their bandedges garner perovskite a wider scope of organic substrate activations.
