title: Fluorescent ratiometric sensing of pyrophosphate via induced aggregation of a conjugated polyelectrolyte.
abstract: Direct detection of pyrophosphate (PPi) in aqueous solution is demonstrated using a cationic poly(phenylene-ethynylene) with polyamine side chains. Pyrophosphate-induced polymer aggregation causes a significant spectroscopic change, which in turn allows quantification of dissolved PPi using ratiometric signals.
