Spectroelectrochemical studies of tin(IV) diphthalocyanine

Synthesis, characterization, and electrochemical and electrochromic properties of sandwich dilutetium tetraphthalocyanine

“…The corresponding DE 1/2 value for [Lu 2 (Pc) 4 ] 4 was found to be 0.98 V which is consistent with the reported values and the sandwich structure of the compound. In contrast to the value for 3, it is much lower than the magnitude of the gap between the first oxidation and first reduction for monophthalocyanines ranging from 1.36 to 1.70 V. 23a-e, 26 The low value of DE 1/2 provides an additional support for the ring-ring interactions in 4.…”

Synthesis, characterization, and electrical and electrochemical properties of sandwich dilutetium tetraphthalocyanine

“…The low value of DE 1/2 for 4 should be a consequence of the splitting of molecular orbitals due to the strong electronic interactions between the p-electron systems of the Pc rings. [10][11][12] The voltammetric behaviours of 3 and 4 in a film on a bare ITO coated glass in contact with an aqueous or non-aqueous (DMSO) solution of KClO 4 were also examined with respect to characteristic colour changes. Fast and stable transitions between the green, blue and purple coloured redox states associated with two well-defined reduction couples were observed clearly for each complex.…”

Selective response mechanism of a platinum disk electrode modified with polyacrylamide membrane conjugated with gallium(III) phthalocyaninate

“…Some investigations concerning the characteristics of metallophthalocyanines in dipolar aprotic solvents have also been carried out by UV-vis spectrophotometric measurement [4][5][6][7]. Some anion sensing materials that were consisted of non-plasticized polyacrylamide polymer (PAA) coupled to phthalocyaninato complex ([Co(pc)], [VO(pc)] and [Sn(pc)]) have been developed for use in dipolar aprotic solutions [8][9][10].…”
