WebJan 20, 2024 · Herein, we report on the synthesis and high-performance liquid chromatography (HPLC) resolution of a new atropisomeric C2-symmetry chiral monomer based on the 3,3′-bithiophene core, which was developed to produce novel, inherently oligomeric chiral electroactive materials. The analytical enantioseparation was optimized … WebChiral SFC separations can be achieved with high efficiency and minimal mobile phase solvent consumption in a short time span. SFC also has benefits in the context of upscaling to preparative scale, since returning to ambient conditions after analysis evaporates the main eluent (CO2) from the mobile phase. ...
