Sažetak
Over the past years we have studied binding and recognition of environmentally relevant anions to polyamine receptor which showed remarkable selectivity towards inorganic or organic anions.4a, c Selectivity in separation was conducted in a series of competitive crystallization experiments. Later, the selectivity trend was extended for the solid state, surpassing the solubility problems of investigated acids. Structural aspects of binding of weakly coordinating anions (such as perchlorate) will be presented and discussed in the context of the conformational space of prepared receptors. In several cases crystals of supramolecular complexes were obtained from gel-phase (preliminary results, emphasize the importance of structural characterization of such phases). Taken altogether, results show how the receptor utilizes its flexibility to ensure the optimal environment for inclusion of target anions in the crystal structure.
