One-dimensional (1D) nanowires exhibit unique anisotropic electronic and optical transport properties, demonstrating broad application prospects in the field of optoelectronic devices. However, undesired stacking structures often compromise the intrinsic advantages of nanowires and obscure the underlying structure-performance relationships. It has been demonstrated that introducing specific spatial configurations into functional building blocks can trigger coupling and synergistic effects. Inspired by this concept, we have constructed various electrochromic devices by manipulating the assembly of electrochromic nanowires with other functional units, aiming to advance their potential applications in smart windows, displays, pressure sensors, among others. The resulting nanowire assemblies not only enhance the macroscopic properties of the materials but also enable functional integration, providing valuable insights for constructing high-performance and multifunctional electrochromic devices.
