Quantifying the Detection Limit of Volatile Organic Compounds by Luminescence Using Trinuclear Silver(I) and Copper(I) Pyrazolate

Abstract

Trinuclear silver(I) and copper(I) pyrozolates have the ability to switch- on luminescence in the presence of volatile organic compounds (VOCs) such as benzene, and switch off in the absence of VOCs. These compounds exhibit the potential for use as VOC detectors in industrial settings where high VOC levels are unsafe for workers, and improving the output of organic light emitting diodes. Trinuclear silver(I) and copper(I) pyrazole complexes have been prepared using solvent mediated, air free schlenk technique under different solvents and a green synthetic route involving mechanical grinding. In depth photoluminescence will be studied using a PTI QuantaMaster 30 Spectrofluorometer with a Kin-Tek gas flow generator attached to observe the response of 1 - 10 ppm of benzene exposure while under room temperature and liquid nitrogen.
