According to the trend observed, the H2TPrOPhOPc was an excellent nonlinear optical limiter when compared to the CoTPrOPhOPc and MnTPrOPhOPc. All the investigated complexes exhibited optical limiting properties comparable to the phthalocyanine complexes reported in the literature. The MTPrOPhOPc complexes were further studied for their electrocatalytic and electroanalytical properties towards the detection of hydrogen peroxide. For the electrocatalytic studies, the synthesized complexes were immobilized onto gold electrode surfaces pre-functionalized with phenylazide (Au-PAz) monolayer. Copper (I) catalyzed alkynyl-azide cycloaddition reaction was used to covalently immobilize the MTPrOPhOPcs onto the gold electrode surfaces to form Au-PAz-MTPrOPhOPc. The MTPrOPhOPcs modified gold surfaces (Au-PAz-MTPrOPhOPc) exhibited good reproducibility and stability in various electrolyte conditions. Electrochemical and surface characterisation of the functionalised gold electrode surfaces confirmed the presence of the MTPrOPhOPcs and their electroanalysis was excellent towards electrocatalytic reduction of H2O2, with the limit of detection (LoD) and limit of quantification (LoQ) in the ^M range. The electrocatalytic reduction peaks for H2O2 were observed at -0.37 V for Au-PAz-MnTPrOPhOPc and -0.31 V for Au-PAz-CoTPrOPhOPc when Ag|AgCl pseudo-reference electrode was used. The Au-PAz-MnTPrOPhOPc and Au- PAz-CoTPrOPhOPc gold electrode surfaces showed good sensitivity and reproducibility towards the electrocatalytic reduction of hydrogen peroxide in pH 7.4 phosphate buffer solution.]]> Thu 20 Apr 2023 09:37:14 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:27491 Thu 13 Apr 2023 14:17:25 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:27487 Thu 13 Apr 2023 13:21:19 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:27482 Thu 13 Apr 2023 10:12:27 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:27456 Thu 13 Apr 2023 09:16:21 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:28694 Thu 02 Dec 2021 20:25:58 SAST ]]>
