Synthesis of a cationic ruthenium(II) complex and its non-enzymatic glucose-sensing properties. New Journal of Chemistry, 47(21), 10187–10194. https://doi.org/10.1039/D2NJ05470A1144-05461369-9261https://doi.org/10.1039/D2NJ05470Ahttps://hdl.handle.net/20.500.12428/5390The new cationic ruthenium(ii) complex (2) was synthesized via the reaction of N,N′-[1,1′-(pyridine-2,6-diyl)bis(ethan-1-yl-1-ylidene)]bis(2-ethyl-6-methylaniline) and [RuCl2(p-cymene)]2, and it was fully characterized using NMR, FT-IR, single-crystal X-ray diffraction, ESI-MS, UV-vis, CV and thermal analysis methods; theoretical computational characterizations and geometric parameters for 2 were also carried out via quantum chemical calculations using the density functional theory (DFT) method. In addition, the synthesized Ru(ii) complex (2) was immobilized on fabricated RGO-TiO2@FTO to evaluate its non-enzymatic biosensing properties, and the sensing properties of the resulting Ru(ii)-RGO-TiO2@FTO electrode were recorded. As a glucose-sensing model, at an applied potential of +0.34 V, the Ru(ii)-RGO-TiO2@FTO electrode presented a moderately good sensitivity of 62.69 μA mM−1 cm−1. Various modifications of Ru(ii)-RGO-TiO2@FTO-type electrodes, such as the metal complex, and material types and ratios, will enable the design of future biosensor devices with improved performance.eninfo:eu-repo/semantics/closedAccessSynthesis (chemical)Quantum chemistrySynthesis of a cationic ruthenium(ii) complexArticle4721101871019410.1039/D2NJ05470AQ2WOS:0009865433000012-s2.0-85161332956
