Construction of Response Patterns for Metal Cations by Using a Fluorescent Conjugated Polymer Sensor Array from Parallel Combinatorial Synthesis
Pattern-based strategy is an emerging field of interest foreffective sensing applications. Seven different conjugated polymers fromcombinatorial synthesis were combined into a sensor array, and sevenmetal cations were selected as representative analytes. The responsepatterns for each cation were constructed by collecting the individualfluorescence responses from seven polymers in the array. Each ion owns acharacteristic pattern. Some of them have similar modes of response withsubtle differences, while some patterns are distinctively different. Thefamily/period the metal cations belong to and the charges/electronicconfigurations they possess may account for such similarity/difference inthe pattern.
