Additional data: Cavity-Containing Supramolecular Gels as a Crystallization Tool for Hydrophobic Pharmaceuticals Open Access

We present two approaches to low-molecular-weight supramolecular gels bearing hydrophobic cavities based on calixarene-containing building blocks. Gels are formed by either a unimolecular approach involving a calixarene based tetrahydrazide gelator or a co-gel apparoach using a calixarene diammonium salt and a bis-crown ether. The calixarene bowl-shaped hydrophobic cavity is designed to enable the complexation of hydrophobic drug molecules in a generic fashion thus providing an anchor site on the surface of the gel fibre to inititate drug crystal nucleation and growth. In this way the gel and active pharmaceutical ingredient comprise a weakly coupled orthogonally self-assembling system under supersaturation conditions. This technique of non-equilibrium orthogonal self-assembly crystallization potentially represents a route to growth of hard-to-nucleate crystals and alternative polymorphic modifications. The co-gel comprising two components holding together by non-covalent ammonium-crown ether interaction can be easily switched back to the sol state by adding competitive binding cations.
