In this contribution, thin poly(ionic liquid) (PIL) coatings with a well-defined pore structure built up from interpolyelectrolyte complexation between a PIL and poly(acrylic acid) (PAA) were successfully used for enhanced solid phase microextraction (SPME). The introduction of porosity with tunable polarity through the highly versatile PIL chemistry clearly boosts the potential of SPME in the detection of compounds at rather low concentrations. This work will inspire researchers to further explore the potential of porous poly(ionic liquid) materials in sensing and separation applications.

The use of highly robust polymeric ionic liquid (PIL) sorbent coatings combined with direct immersion (DI) and headspace (HS) modes in a single solid-phase microextraction (SPME) procedure coupled to gas chromatography (GC) is reported.
