Synthesis and electrochemical properties of new cobalt and manganese phthalocyanine complexes tetra-substituted with 3,4-(methylendioxy)-phenoxy
TL;DR: In this article, the synthesis and electrochemical properties of new cobalt and manganese phthalocyanine complexes, tetra-substituted with 3,4-(methylendioxy)-phenoxy at the peripheral (complexes 3 and 5) and non-peripheral (complexs 4 and 6) positions, are reported.

Graphene quantum dots anchored onto mercaptopyridine-substituted zinc phthalocyanine-Au@Ag nanoparticle hybrid: Application as fluorescence “ off-on-off ” sensor for Hg 2+ and biothiols
TL;DR: The designed hybrid was employed as a dual fluorescence nanoprobe for Hg2+ and biothiol detection in aqueous solution using PEI-GQDs as the fluorescence switching signal probe and was found to be highly stable and selective towards the target analytes in the presence of other amino acids and metal ions.

Tuning the physico-electrochemical properties of novel cobalt (II) octa[(3,5-biscarboxylate)-phenoxy] phthalocyanine complex using phenylamine-functionalised SWCNTs
TL;DR: In this paper, the physical and electrochemical properties of the cobalt octa[(3,5-biscarboxylate)-phenoxy] phthalocyanine (CoOBPPc) complex were evaluated using spectroscopy (IR and UV-vis), field emission scanning electron microscopy and electrochemistry (cyclic voltammetry, electrochemical impedance spectrography).
