The synthesis, characterization and X-ray diffractometry structure of fluorine-containing cyclobis(paraquat-p-phenylene) tetracation

Add time:08/30/2019    Source:sciencedirect.com

Two novel fluorine-containing cyclophanes 1 and 2 incorporating a 1,4-bismethylfluorophenylene subunits have been synthesized via the template-directed clipping methodology and their structure was characterized by 1H NMR, 13C NMR, MALDI-TOF-MS and elemental analysis. X-ray diffraction analysis of the solid state molecular structure showed that the complex units are linked by non-classical C–H⋯F hydrogen bonding.
