β¦ Synopsis
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 Cs, Cl0 and Cl2 alkyl chains) has been prepared and is found not to act as quenchers and hence, represent an improved class of plasticizers for use in luminescence-based sensors.

AbstractΓThe synthesis and photophysical behavior of a luminescent chemosensor for the early lanthanide elements is described. The sensor is a 1,4-diphenylethynyl-benzene chromophore having 18-crown-6 moieties bound to the outer phenyl rings. The chromophore is luminescent and the emission is quench
