Binary thin films of cobalt(II) phthalocyanine (CoPc) and cobalt(II) tetraphenylporphyrin (CoTPP) were prepared at submonolayer coverage on Au(111)/mica substrates byvapor deposition. All sample preparation and analysis were done under an ultrahigh vacuum. Scanning tunneling microscopy (STM) constant-current images of CoPc/CoTPP mixtures showed two close-packed surface structures, with differen...
The optical and electrical properties of terbium(III) bis(phthalocyanine) (TbPc2) films on cobalt substrates were studied using variable angle spectroscopic ellipsometry (VASE) and current sensing atomic force microscopy (cs-AFM). Thin films of TbPc2 with a thickness between 18 nm and 87 nm were prepared by organic molecular beam deposition onto a cobalt layer grown by electron beam evaporation...
This paper describes the electrocatalytic behaviour of a glassy carbon electrode (GCE) modified with cobalt(II)phthalocyanine (CoPc) complex peripherally tetrasubstituted with cobalt(II)tetraphenylporphyrin (CoTPP) complexes via ether linkages (i.e., CoPc-(CoTPP)4). The features of the immobilised pentamer were interrogated with cyclic voltammetry and electrochemical impedance spectroscopy (EIS...
The development and implementation of technology that can capture transform carbon dioxide (CO2) is ongoing interest. To end, the integration molecular electrocatalysts into devices appealing because desirable features molecules, such as ability to modify active sites. Here, we explore how identity aliphatic group in 1,4,8,11,15,18,22,25-octaalkoxyphthalocyanine cobalt(II) affects catalytic beh...
A modified method for the synthesis of metallooctachlorophthalocyaninesand methods their purification based on sequential treatment with hydrochloric acid (10%) sodium hydroxide (2M), then again (10%), pyridine (O.S.C.) in 1,2,4-trichlorobenzene as a solvent is presented. As result, degree copper ion complexes was achieved, 99% versus best result using known literature 93%, cobalt purity 98% 88...
