Abstract
The performance of sophisticated devices not only rely on the chemical structures of materials, but also strongly depend on nanoarchitectures in its solid state. It is well-known that solution-based fabrication is key to unlocking the potential of low-cost, flexible, and light electronic devices. Unfortunately, it is extremely complicated to integrate the multiscale and multicomponent of molecules and nanoparticles into nanostructural films. An exceptional C–C coupling reaction of carbazyls, electrochemical layer-by-layer (LBL) assembly with an accelerating electric trigger, used as a low-cost solution-processed method, has emerged to manipulate various molecules and nanoparticles into scale- and component-controllable thin films. In contrast to the conventional methods of thin film preparation, the molecular weight, solubility, and film-forming ability are not necessarily obstacles. With an electric current as reagent, the total energy consumption can be reduced, and the unstable and hazardous reagents can be generated in situ. This electrochemical LbL assembly has already been recognized as rapid and covalent LbL methodology for the of photoelectric films.
