In this study novel tetra furfurylamide substituted metal phthalocyanine (M=Co, Cu, Ni & Zn) were synthesized and characterized by elemental analysis, Ultra-violet, Fourier transfer infrared spectroscopy, mass spectroscopy and powder X-ray diffraction analysis. The cobalt (II) tetra furfurylamide phthalocyanine (CoTfurNH2Pc) tailored GCE was constructed by drop covering technique. The fabricated electrode was subjected for electrochemical investigation of oxidizable species such as dopamine (DA), uric acid (UA) and reducible moiety like dimetridazole (DMZ). It was noticed that CoTfurNH2Pc/GCE exhibits admirable electrochemical performance for dopamine, uric acid oxidation and dimetridazole reduction in PBS pH 7. 0. The sensor exhibits sensitivity for DA (CV 0. 179, DPV 0. 333, CA 0. 486 μ A μ M-1cm-2), for UA (CV 0. 517, DPV 0. 374, CA 0. 129 μ A μ M-1cm-2), for DMZ is (CV-8. 55, DPV-13. 73, CA-0. 393 μ A μ M-1cm-2) respectively (S/N=3). Biomolecules present in same solution can be sensed by constructed electrode with peaks resolution of 348 millivolts and 318 millivolts for dopamine-dimetridazole and dimetridazole-uric acid respectively. The CoTfurNH2Pc fabricated electrode has various useful properties like high repeatability, quick response and steadiness. Further DPV and chronoamperometric of titled compound has been studied.

Study of the removal of blocking groups in redox polymer precursors, poly(5-vinyl-1, 3-benzodioxole) (polymer 1) and poly(2, 3-dimethoxystyrene) (polymer II), was undertaken with different acidic reagents. Boron trichloride dodecyl mercaptan (RSH) system showed a better cleaving performance among the experimented reagents. Poly(4-vinylcatechol), initially methanolsoluble, became purple-coloured with a defied insolubility under aerobic conditions. Intramolecular cross-linking is viewed as a possible explanation for the observed insolubility of the obtained resin; that is, either benzene rings of two moieties undergo an intramolecular Pummerer reaction. A mechanism of the deportation of the redox polymers seems to be substituent-dependent polymer precursors. Indeed. poly(3-vinylcatechol) remained methanol-soluble for months with a faint pink colour. Redox midpotentials of poly(3-vinylcatechol) were established to be 707 mV at 23 °C, while that of catechol was found to be 764 mV under the same conditions.

Zinc ferrite (ZnFe2O4) is one of the famous and widely studied photocatalysts with band-gap in the visible region.  ZnFe2O4 has emerged as a promising photocatalyst due to its unique properties and versatile applications. This review aims to provide an overview of the properties, synthesis methods, and photocatalytic performance of zinc ferrite. It also explores the diverse applications of zinc ferrite composites as catalysts, highlighting their performance as photocatalysts. The catalyst possesses a spinal fine crystalline structure and can be prepared by various methods such as combustion, hydrothermal, sol-gel, and co-precipitation. Zinc ferrite by nature is a superparamagnetic semiconductor that has been used for the degradation of numerous organic dyes in the past. ZnFe2O4 is particularly effective in harnessing light energy and actively supports photocatalytic-redox reactions.
