ABSTRACT
Advanced neutron scattering techniques have the unique advantages of comprehensively characterizing the hierarchical structure and dynamic behavior of molecular clusters (MCs) at a wide range of spatial and temporal scales. Therefore, the application of neutron scattering techniques can provide spatiotemporal information of MCs concerned about both the structure and dynamics topics. This will help us to get insight into their structure-property relationships and guide the rational design of MCs-based functional materials applicable for diverse application scenarios. -

ABSTRACT
Solventless mechanochemical synthesis by manual grinding was applied to grow imidazole-succinic acid (C3H4N2-HOOC(CH2)2COOH) and imidazole-glutaric acid (C3H4N2-HOOC(CH2)3COOH), which exhibit different electric conducting behaviors and activation energies Ea compared with the reported single crystals obtained from the solution method. This method bears strong capability for tuning conductivities and achieves complete deuteration of the organic salts. -
