Histidine-dialkoxyanthracene (HDA) was synthesised as a turn off type fluorescent sensor for fast and sensitive detection of mercury ions (Hg2+) in aqueous media. The two histidine moieties act as ‘claws’ to selectively complex Hg2+. The binding ratio of HDA to Hg2+ was 1:1 (metal-to-ligand ratio). The association constant for Hg2+ towards the receptor HDA obtained from Benesi–Hildebrand plot was found to be 3.22?×?104?M?1 with detection limit as low as 4.7?nM (0.94?μg/L).

-
Page/Page column, (2015/02/05)
The invention relates to siloxane polymer comprising a central polysiloxane polymer block B with organofunctional radicals, which are terminal or bonded laterally on the polymer block, comprising IPDI and amino acid derivatives which are covalently bonded via a hydrophobic or hydrophilic linker group Q1′, Q2′, and to compositions comprising these siloxanes. Furthermore, processes for their preparation and their use are disclosed.
