Abstract
Applicant discloses a sensing element for sensing an organic chemical analyte, comprising a first electrode and a second electrode, and a microporous, hydrophobic, analyte-responsive dielectric material disposed at least in proximity to the first and second electrodes. The analyte-responsive dielectric material may be an amorphous random covalent network comprising a mean pore size of less than about 10 nm and a porosity of at least about 20%. An electrical property of the sensing element, such as capacitance, can be monitored in order to sense an organic chemical analyte.
