Printable organic sensors fabricated from solution-processed π-conjugated polymers (π-CPs) are promising candidates to detect volatile organic compounds (VOCs) due to the intriguing phys., chem. and electronic properties of π-CPs. These devices, often termed organic chemiresistors, require good sensing capabilities to transduce stimuli from specific VOCs at low concentrations into anal. elec. signals. However, discriminating such VOCs using organic chemiresistors proved very challenging. Herein, the authors report that the mol.-level electrochem. doping of π-CPs with solid-state ionic liquids (SILs) significantly improves their elec. conductivity (~10-1 S cm-1) and selective VOC interactions, which can be manipulated through different π-CPs:SIL blend ratios. These characteristics enable the fine discrimination of VOCs at concentrations in the parts-per-billion (ppb) range under low power consumption (<0.1 μW) and room temperature conditions. The authors′ result provides a new opportunity for developing highly sensitive and selective VOC monitoring platform technologies that are printable on large-area, wearable, flexible and transparent substrates.
