Sensing of polymeric sensor-based rhodamine B derivative for metal cations in complete aqueous solution

“…The copolymers of traditional monomers with some polymerizable fluorescent units display intensive fluorescence. For many acrylic monomers bearing chromophore, Li et al [16] and Cui et al [17] found that the fluorescent intensity of the polymerizable fluorescent monomer is dramatically lower than those of its polymer or copolymer in the same chromophore concentration, due to the 'structural self-quenching effect' [18]. Moreover, the covalent bonding of the fluorophores to the polymer chain provided good stability to solvents and migration, improving their environmental behaviours [19].…”
