Abstract

We have investigated the optical and electrochemical changes of the azastilbene, dimethyl-[4-(2-quinolin-2-yl-vinyl)-phenyl]-amine (DQA), with four organothiophosphorus (OTP) pesticides: ethion, malathion, parathion, and fenthion. Significant changes in UV-visible absorbance wavelength and in electrochemical signals indicate the effectiveness of DQA as an OTP sensor. © 2010 Elsevier Ltd. All rights reserved.
