Organic multishell isostructural host-guest crystals: fullerenes C-60 inside a nitroxide open framework
Abstract
The dinitroxide biradical bTbk crystallizes forming hexagonal open frameworks with one-dimensional corrugated channels filled with crystallization solvent. The large pockets constitutive of the channels allowed the inclusion of C-60 in the paramagnetic network. The rapidity and high fidelity of crystal growth were used to prepare isostructural multilayer host-guest crystals successively stained with C-60.
