Synthesis of a Fluorescent Solvatochromic Resin Using Suzuki-Miyaura Cross-Coupling and Its Optical Waveguide Spectra to Measure the Solvent Polarity on the Surface.

ABSTRACT: 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 resin and 5-[4-(N,N-dihexylamino)phenyl]-2-thienylboronic acid N-methyl-iminodiacetic acid (MIDA) ester. The optical waveguide spectrometry studies on the resin showed a strong fluorescent solvatochromism in various organic solvents.
