ConspectusStimuli-responsive materials have a great potential in various novel photoelectric devices, such as self-adaptive adjustment intelligent detection, molecular computers with information storage capability, camouflage and anticounterfeiting display, energy-saving displays, others. However, progress related areas has been relatively slow because of the lack high-performance smart limitations available reaction mechanisms currently. To address these problems fundamentally, new need to be designed developed, learning from nature is an effective method achieve this long-awaited target, mimicking proton transfer processes at molecular/supramolecular level. The stimuli-induced reversible system composed that release or capture protons response stimuli switch molecules control color and/or fluorescence modulation by protons, it applied stimuli-responsive including bistable electronic/electrochromic electrofluorochromic water-jet rewritable paper, visible-light-responsive mechanochromic materials.To help researchers gain deep insight into transfer, we attempted summarize its mechanism design principle, discuss strategies prepare devices. This Account discusses different systems which color/fluorescence change induced process under stimuli, electric field, water, light, heat, stress. Relative very promising applications well their performance especially for environmentally friendly devices are then summarized, electrochromic paper. Meanwhile, focus on key influence factors useful additives improving device's performance. At last, challenges bottlenecks faced based proposed. Moreover, put forward some suggestions solving limitations.These exciting results reveal extremely attractive possess next generation energy resource saving environmental protection display. We hope further prospers field discoloration next-generation green displays.
