Novel and Innovative Interface as Potential Active Layer in Chem-FET Sensor Devices for the Specific Sensing of Cs+

Abstract: An innovative novel interface has been designed and developed, in order to be used as a potential active layer in Chem-FET sensor devices for the specific sensing of Cs +. In this study, the synthesis of a specific Cs + probe based calix[4]arene benzocrown ether, its photophysical properties as well as its grafting onto a single lipid monolayer (SLM) recently used as efficient ultrathin organic dielectric in Chem-FETs are reported simultaneously. On the basis of both optical and NMR titration experiments, the … Show more

“…The full synthesis of the cesium's probes was described elsewhere, following reported literature procedures for analogous compounds [35][36][37][38][39][40]. The probes have demonstrated high affinity constants toward Cs + (6024 M -1 ) while for the most competitive ions such as Rb + and K + the latter was about two-fold magnitude lower respectively (2288 M -1 , 2825 M -1 ) [34]. Note that no affinity was found for Na + ions.…”
