Chemodosimeters and 3D inorganic functionalised hosts for the fluoro-chromogenic sensing of anions

摘要: Abstract We report here recent examples developed in our research group on the development of novel chemodosimeters for fluoro-chromogenic anion sensing. For instance, squaridine, pyrylium and pent-2-en-1,5-dione dye scaffoldings have been used to obtain highly specific chromo-fluorogenic responses anions such as cyanide, sulfide or certain carboxylates water mixed aqueous solutions. will also new use “smart sensory materials” based nanoscopic inorganic structures bio-mimetic hosts These systems combine molecular ideas 3D solid pre-organised features design concepts organic/inorganic hybrid materials recognition/sensing protocols. functionalisation siliceous mesoporous with ureas, thioureas, guanidinium groups saccharides suitable dyes has resulted enhanced sensing anionic species fatty acids, citrate borate.
