Abstract

To carefully design sensing materials and to master their processing is of the utmost importance to get efficient sensors and optimize their performances for air quality monitoring (AQM). Beside inorganic materials and carbon nanomaterials, molecular materials, including macrocyclic molecules and conjugated polymers play an increasing role in the field of chemical sensors. In this mini-review devoted to molecular materials, we chose to separate sensing materials in three main categories, namely macrocyclic molecules, polymers and hybrid materials involving compounds from the two previous categories. Among macrocyclic molecules, the most important families used in chemosensing are phthalocyanines and porphyrins. Among other molecules used as gas sensing materials, cavitand compounds, e.g. resorcinarenes, offer the possibility to form inclusion complexes with volatile organic guests, which involve host-guest intermolecular interactions. Polymers used for AQM can be classified in two main categories, namely conjugated polymers, often associated with conductometric transducers and dielectric polymers in capacitive sensors. Generally speaking, the choice of the sensing materials depends not only on the target species, but also on the transduction mode, and must be envisaged according to particular applications.
