Multicolor Management of Smart Fluorescent Polymeric Hydrogels

Fluorescent polymeric hydrogels (FPHs) are rising stars of luminescent materials because of their considerable prospects in a wide range of advancing domains. However, challenges exist in broadening their color tunability, which is the key to developing multicolor FPHs (MFPHs) for actual applications in cutting-edge frontiers. In this perspective, we summarize the state-of-the-art strategies for fabricating MFPHs and discuss the remaining challenges.
