Fluorescent chemosensors based on conjugated polymers has been an active research area for over a decade. While a great deal of study has focused on the polymer backbone, there is a need for an increasing array of receptors. We are currently developing the synthesis of conjugated fluorescent organic polymers containing dipyridylquinoxaline. Two systems have been developed; poly (phenylene ethynylene) (DPQ-PPE) and dipyridilquinoxaline poly (phenylene ethynylene thiophene ethynylene) (DPQ-PPETE). These polymers are designed to serve as sensors for the detection of transition metal cations, listed by the Environmental Protection Agency (EPA) as toxic to the environment. The complete synthesis of these polymers will be presented including characterization of each intermediate. The polymers were initially characterized by NMR and IR spectroscopy in order to confirm the correct product and purity.
