Luminescence and Electrochemical Properties of Organostannoxane Coordination Polymer Based on Ferrocenyl-2-Cyano Carboxylate Ligand

Abstract

Organostannoxane-based multiredox assemblies containing ferrocenyl peripheries have been readily synthesized by a simple one-pot synthesis, with quantitative yields. The reaction of triorganotin oxides, (nBuSn)2O with 2-cyano-3-ferrocenyl acrylic acid leads to the formation of [(nBu3SnOC(O)CNCHFc)n] polymeric structure. FT-IR, NMR, UV-Vis and emission spectroscopic techniques were performed for the characterization of [(nBu3SnOC(O)CNCHFc)n](Fc = η 5 C5H4-Fe-η 5 C5H4) polymeric structure. Electrochemical studies on these hybrid organotin/ferrocene systems reveal that most of them exhibit a single quasi-reversible oxidation peak.

Electrochemical Applications of Ferrocene‐Based Coordination Polymers

“…[32] The redox potential of CPs mainly depends on the electrondonating or electron-withdrawing ability of their substituents. [46] Li et al demonstrated that electron-withdrawing moieties hinder the oxidation of the ferrocenyl units they are attached to. For example, the oxidation potentials of the CPs of HOOCCH=C(CH 3 )Fc with different metal ions exceeded that of the free HOOCCH=C(CH 3 )Fc moiety.…”

“…For example, the oxidation potentials of the CPs of HOOCCH=C(CH 3 )Fc with different metal ions exceeded that of the free HOOCCH=C(CH 3 )Fc moiety. [46] Metal ion characteristics can also affect CP redox properties. Li et al [47] synthesized two analogous CPs containing Mn/Cd ions, Fc carboxylate, and a flexible elongated nitrogen-containing heterocyclic ligand.…”
