The Synthesis Of Chemosensors For Toxic Analytes, Johnathan Hugh Broome Aug 2016

The Synthesis Of Chemosensors For Toxic Analytes, Johnathan Hugh Broome

Dissertations

A number of chemosensors have been designed and synthesized to target cations (Zn2+ions), neutral molecules (cathinones), charged molecules (aminoindanes), and anions. The Zn2+ ion sensor featured bistriazole designed binding unit and ferrocene signaling units. Characterization of Zn2+ ion binding was carried out with electrochemical techniques (CV and DPV), 1H-NMR, mass spectrometry, and molecular modelling. It exhibited a 1:1 binding stoichiometry with Zn2+ and had an affinity for ZnCl2 (Log K1:1 = 4.1 ± 0.02) over other Zn2+ salts.

The cathinone probe was designed to selectively bind mephedrone over common ...
