In this study, we have investigated the dynamic behavior of colloidal rods within their isotropic phase, employing multispeckle ultrasmall-angle x-ray photon correlation spectroscopy (UA-XPCS) focusing on the understanding of the interplay between structure and dynamics at the nearest-neighbor length scale. While prior research has primarily focused on the structural aspects, our work addresses the lesser-explored realm of dynamic behavior. Through ultrasmall-angle x-ray scattering and UA-XPCS, we have measured the key parameters, such as the effective structure factor (Seff(q)) and the effective diffusion coefficient (Deff(q)). A significant finding is the scaling relationship between Deff(q) and 1/Seff(q), implying a connection between particle diffusion and structural arrangement. Additionally, the estimated scaling parameter (effective amplitude function, Aeff(q)), which can be directly related to the effective hydrodynamic function (Heff(q)) shows a similar dependence on wave vector (q) as Seff(q). Furthermore, our study precisely determines the volume fraction at which the arrest transition occurs. These findings shed light on the influence of structures on the intricate dynamics of anisotropic colloidal systems.
