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.
