Deposition of Ni(II)Porphyrin monolayer on the gold electrode via azide-alkyne click - coupling and its electrochemical characterization
In this work, a Ni(II) porphyrin containing two azide groups ((N-3)(2)-Ni(II) porphyrin) was applied for gold electrode modification via azide-alkyne click reaction. The [CuBr(PPh3)(3)] catalyst was used for the cycloaddition of diazido Ni(II) porphyrin to alkyne functionalized thiols previously assembled onto the gold surface. The self-assembled monolayer (SAM) incorporating Ni(II) porphyrin was characterized in aqueous solutions by cyclic voltammetry (CV), Osteryoung square-wave voltammetry (OSWV) and differential pulse voltammetry (DPV). The attachment of a ssDNA probe via a strained bicyclononyne group to the developed redox active monolayer via copper-free alkyne-azide click ligation is presented.

Abstract
In this work, a Ni(II) porphyrin containing two azide groups ((N-3)(2)-Ni(II) porphyrin) was applied for gold electrode modification via azide-alkyne click reaction. The [CuBr(PPh3)(3)] catalyst was used for the cycloaddition of diazido Ni(II) porphyrin to alkyne functionalized thiols previously assembled onto the gold surface. The self-assembled monolayer (SAM) incorporating Ni(II) porphyrin was characterized in aqueous solutions by cyclic voltammetry (CV), Osteryoung square-wave voltammetry (OSWV) and differential pulse voltammetry (DPV). The attachment of a ssDNA probe via a strained bicyclononyne group to the developed redox active monolayer via copper-free alkyne-azide click ligation is presented.
