Abstract

Single-molecule magnets (SMMs) were tested for their chemical sensing properties on photo-electric chemical sensors. Photo-electric chemical sensors or PECS are contact sensors for the detection of various chemical analytes, with a wide range of possible applications, using different analyte-recognition compounds (ARCs). The ARC-analyte interaction on the surface of the sensor generates photovoltages (PVs), due to the Becquerel effect, as in photovoltaics. Detection of analyte is documented as modified PVs upon excitation of both the analyte and the ARC using an optical source providing fast light flashes (<10 μs). Single crystals of the SMMs were grown, and were applied mechanically on the PECS electrodes. The background-corrected data revealed significant ARC activity for the two SMMs considered, namely [Mn12O12(O2CCH3)16(H2O)4]·2CH3COOH·4H2O, and [Mn12O12(O2CPh)16(H2O)4], for vapor and liquid analytes, respectively.
