Solid and liquid supramolecular complexes by solid-solid mechanosynthesis.

Green mechanosynthesis, free solvent, has been used for preparing a series of supramolecular complexes. Through directional hydrogen bonds and π-cation interaction can be prepared complexes with different states of aggregation of matter, where stoichiometry plays an essential role. When the stoichiometric ratio between the two compounds was 1:1, a solid product is obtained. But, when the ratio is higher, products are obtained as gel or paste to reach low viscosity liquids. Also, the structure of such complexes that form three-dimensional aggregates between C 12 TAC and phenol derivatives can explain the different aggregation states for final products and this may be the key to understand the viscosity reduction mechanism.
