A New Conjugated Polymer Chemosensor Functionalised with 2,6-Bis(1,3,4-oxadiazole-2-yl)pyridine for Metal Ion Recognition

Abstract

Abstract A new conjugated alternative copolymer based on 2,6-bis(1,3,4-oxadiazol-2-yl)pyridine and 9,9-dialkylfluorene in a main chain showed strong blue fluorescence with band maxima at 389 nm and 405 nm in the 1,2-dichloroethane solution and posessed sensitivity to various metal ions such as Ni2+ and Fe3+ as a fluorescence-mode chemosensor.
