Dibenzo-24-crown-8 can be used as a molecular transporter in the formation of [1]rotaxanes with thiazolium-based mono- and tris-branched ammonium ions. It is also used as a co-solvent and phase-transfer catalyst for cesium fluoride, to the development of a more efficient anhydrous fluorinating system for organic synthesis.
Recrystallise it from EtOH, and dry in a vacuum at 60o over P2O5 for 16hours. [Delville et al. J Am Chem Soc 109 7293 1987, V.gtle ed. Top Corr Chem (Host Guest Complex Chemistry) 98 1981.]
