Encapsulation of sodium alkyl sulfates by the cyclotriveratrylene-based, [Pd6L8]12+ stella octangula cage

Abstract

We have previously described a cyclotriveratrylene (CTV)-based complex, [Pd6L8]12+, that forms a highly symmetric stella octangula cage. Here we report on the ability of this system to host sodium salts of three alkyl sulfates; octyl (SOS), dodecyl (SDS) and tetradecyl (STS). 1H NMR chemical shift and diffusion coefficient measurements reveal that two molecules of alkyl sulfate reside in the cage, though rapid exchange between cage and bulk solvent is apparent. Host : guest association constants have been determined and support for the internalisation of the sulfates is available from 2D ROESY and NOESY data.
