ABSTRACT
A novel fluorescein-based probe FLA-Boe was developed for detecting H2O2. Modified by 2-Bromomethylphenylboronic acid pinacol ester, FLA-Boe is a Fluorescein derivative with eminent photostability and remarkable H2O2 sensitivity and selectivity. FLA-Boe was utilized to synthesize hydrogel sensors in the manner of guest-host interaction by taking advantage of its aforementioned features. The hydrogel sensor can be used to detect H2O2 effectively in both flowing and static water environments with satisfactory performance. It is expected that this application may open a new page to develop a neoteric fluorescent property analysis method aiming at H2O2 detection.
ABSTRACT
A mercury ion sensitive fluorescent functional monomer was synthesized based on rhodamine 6G, and two highly-effective approaches about the research and development of novel macroscopic hydrogel sensor were reported. The monomer was utilized to synthesize hydrogel sensors by free radical polymerization and guest-host interaction. Hydrogel sensors have prominent selectivity to Hg2+ and can be tailored and reused, which are capable of detecting Hg2+ sensitively in flowing and standing water environment with satisfactory performance. This work is expected to open an avenue to construct novel fluorescent analysis method for Hg2+ detection.
