Abstract/OtherAbstract:
Here we demonstrate the fabrication, characterization and tailoring of porous organic nanomembranes and their direct integration on inorganic substrates for sensing applications. The chemically prepared nanomembranes can be integrated on both conducting and insulating substrates by either transfer or direct synthesis. We also successfully demonstrate their use for the detection of commonly used acids including HCl, H<u>2</u>SO<u>4</u> or H<u>3</u>PO<u>4</u>, and their respective counterions - chlorides, sulfates and phosphates. Impressively, the in-situ acid detection is achieved down to 5 nmol.L(-1), while the quantification is feasible between 5 µmol.L(-1) and 10 mmol.L(-1). These values are among the lowest values reported so far in literature. Furthermore, the organic nanomembrane based sensor covers a wide concentration range of almost 8 orders of magnitude including the environmental limits currently adopted.
