Abstract Numerous otherwise difficult applications have been realized with materials, the chemical/physical properties of which can be controlled by external stimuli such as heat, pressure, photo‐irradiation, and voltage bias. However, complexity design lack easy‐to‐conduct synthetic methods make creation on‐demand responsive materials a formidable task. Here we report an electric‐stimuli‐responsive multifunctional material, [10]CPP‐I : crystalline assembly hydrocarbon nanoring ([10]cycloparaphenylene: [10]CPP) “electro‐responsive porous host” iodine “potentially functional molecule”. Through applying electric stimulus, turned to exhibit two attractive properties: electronic conductivity white light emission. We revealed that trigger cascade formation polyiodide chains inside [10]CPP through charge transfer, leading emergence these properties. This “responsive approach is expected applicable for different stimuli, opens path devising generic strategy development stimuli‐responsive materials.
