Recently, we also reported the synthesis and oxygen-sensing ability of poly(IBM-co-TFEM) bearing PtTPP.33 The conjugation of dye with polymer results in a distortionless Stern–Volmer plot, indicating reduced microheterogeneity. As a fluorescent temperature sensor, Iwai et al. reported poly(N-isopropylacrylamide) bearing polarity-responsive fluorescent molecule.32 Their sensor responds to temperature with an excellent sensitivity.
