Dynamic control of molecular photoluminescence offers chemical solutions to designing functional emissive materials. Although stimuli‐switchable molecular luminescent systems are well established, how to encode these dynamic emissive systems with a “timing” feature, that is, time‐dependent luminescent properties, remains challenging. This Concept aims to summarize the design principles of dynamic timing molecular photoluminescent systems by discussing the state‐of‐the‐art of this topic and the shaping of fabrication strategies at both the molecular and supramolecular levels. An outlook and perspectives are given to outline the future opportunities and challenges in the rational design and potential applications of these smart emissive systems.
Time is more! A review of how molecular emissive properties can be controlled in a dynamic time‐dependent manner to give compounds that show great potential for designing smart luminescent materials with time‐encoding features.
