Electrochemically oxidized 15-crown-5 substituted thiophene and host-guest interaction with new psychoactive substances
Original language description
The aim of this work is to develop an impedimetric sensor using the principle of host- guest interaction for the detection of new psychoactive substances (NPSs). Synthesized 4 -( N -3- thiophenecarboxamido)benzo-15-crown-5 (TH3CA4AB15C5) was electrochemically deposited on the sur- face of a platinum disc electrode using cyclic voltammetry. Spectroscopic (infrared and NMR spec- troscopy) and electrochemical impedance spectroscopy (EIS) studies were applied to confirm the struc- ture of the polymeric film deposited onto the electrode surface and to evaluate its affinity towards 2- aminoindane (AI), 2-(methylamino)-1-phenylbutan-1-one (buphedrone, MABP) and 3 ,4 -methylenedioxy- α-pyrrolidinopropiophenone (MDPPP). These studies showed that the ease of formation hydrogen bonds between the product of electrochemical oxidation (TH3CA4AB15C5) and the above-mentioned analytes is the dominant factor for obtaining a useful analytical signal. The changes in the resistance to charge trans- fer obtained during the EIS measurements allowed: i ) to separately measure both the synthetic cathi- nones (MABP, MDPPP) and AI in the concentration range 1.99 x 10 –5 –1.22 x 10 –3 M; ii ) to quantify AI at levels of (1.6 –3.0) x 10 –4 M in the presence of various representatives from the NPS family.
