A polymer based fluorescence “turn-on” chemosensor is demonstrated with high sensitivity and selectivity towards Fe2+ cations. This system is an inorganic/organic hybrid system in which Cu2+ is coordinated at the receptor site of a conjugated polymer sensor. The unique quenching behavior of the Cu2+ towards this conjugated polymer was used to lower the initial fluorescence intensity of the sensory system. This results a highly sensitive and also selective sensory system towards Fe2+ as compared to other related divalent transition metal cations in solution.
