Yu Otsuka et al.
Materials (Basel, Switzerland), 13(20) (2020-10-15)
We have established a novel analytical method for solvent polarity on resin surface by combining the synthesis of fluorescent solvatochromic resin with optical waveguide spectrometry. The fluorescent solvatochromic resin was obtained via Suzuki-Miyaura cross-coupling between 4-iodobenzoic acid immobilized on Wang
