Abstract

AbstractNovel nitric oxide (NO) responsive monomers (NAPMA and APUEMA) containing o‐phenylenediamine functional groups have been polymerized to form NO‐responsive macromolecular chains as truly biomimetic polymers. Upon exposure to NO—a ubiquitous cellular signaling molecule—the NAPMA‐ and APUEMA‐labeled thermoresponsive copolymers exhibited substantial changes in solubility, clearly characterized by tuneable LCST behavior, thereby inducing self‐assembly into nanoparticulate structures. Moreover, the NO‐triggered self‐assembly process in combination with environmentally sensitive fluorescence dyes could be employed to detect and image endogenous NO.
