Abstract

Polyelectrolyte gels are promising soft networks that can accommodate various guest species and retain liquid nature. The incorporation of two novel silica based terbium complexes (Tb(a)₂ and Tb(b)₂) in the poly(acrylamide) host can exhibit the characteristic green terbium emission in water. More interestingly, we noted that these target materials can selectively recognize H₂PO₄^- (detection limit 10^-5 M) and HSO₄^- (detection limit 5 × 10^-5 M) compared with other anions, such as F^-, Cl ^-, Br^-, and I^-. The fluorescence intensity ratios against both anions (H₂PO₄^- and HSO₄^-) concentration all follow the simple linear equations by the least-squares fitting method. © 2011 American Chemical Society.
