Perylene dyes are known for their high absorption coefficients, high quantum yields and excellent photo-stability. Furthermore, these molecules are known to undergo photoinduced electron transfer (PET), which makes them highly suitable for sensor applications. In our contribution, we present a modular approach towards polymeric pH-sensors by combining a perylene-derived monomer with pH-sensitive comonomers. An additional feature is added by copolymerization of monomers bearing oligo(ethylene oxide). Such materials have the additional feature of phase separation driven by increasing temperature, called LCST (lower critical solution temperature) effect. Future endeavor in our group will be directed towards more detailed characterization of the photophysical properties of the obtained materials. Furthermore, variations in polymer design and incorporation of other pH-sensitive co-monomers will be conducted.
