  1,4-Diazobicyclo(2,2,2)octane-modified multi-ammonium derivatives as ratiometric fluorescent sensors for lipopolysaccharide

  摘要：

  A series of pyrene derivatives bearing multi-quaternary ammonium 1,4-diazobicyclo(2,2,2)octane groups were synthesised as ratiometric fluorescent sensors for lipopolysaccharide (LPS) in aqueous solution. Ratiometric changes in fluorescence spectra of the sensors were observed from the pyrene monomerexcimer conversion which is modulated by the supramolecular self-assembly between sensors and LPS. These sensors show high selectivity towards LPS with the detection limit down to tens of nanomolar levels. The interaction mechanism between the sensors and LPS was also discussed.
