Supported thin flexible polymethylhydrosiloxane permeable films functionalised with silole groups: new approach for detection of nitroaromatics

Novel re-useable luminescent sensors highly sensitive to quenching by nitroaromatic compounds in both solution and the vapour phase have been developed by covalently bonding a new allyl-substituted silole into substrate-supported crosslinked polymethylhydrosiloxane (PMHS) thin films by Pt-catalyzed hydrosilylation of the SiH groups.
