摘要：

The widely used polar plasticizer 2-nitrophenyl octyl ether (NPOE) is found to act as a dynamic quencher of the luminescence of certain indicators; quenching studies have been performed both in solution and sensor membranes plasticized with NPOE. A series of 2-cyanophenyl alkyl ethers (with C-8, C-10 and C-12 alkyl chains) has been prepared and is found not to act as quenchers and hence, represent an improved crass of plasticizers for use in luminescence-based sensors.
