Synthesis, X-Ray Structure and (Spectro)electrochemical Study of an Electrochromic Iron(II) Chlathrochelate with Tuned Redox Properties

Abstract

A boron-capped tris-dioximate iron(II) bis-macrocyclic clathrochelate with annulated dimethylquinoxaline heterocycle has been synthesized. The compound has been characterized with single-crystal X-ray diffraction, multinuclear NMR, IR, UV-vis spectrometry, CV and spectroelectrochemistry. The clathrochelate is capable of ligand-centered two-electron reversible reduction coupled with electrochromism (in solution and thin film).Keywords: Macrocyclic compounds, clathrochelates, iron complexes, ligand reactivity, electrochromism.синтез, строение и (спектро)электрохимическое исследование электрохромного клатрохелата железа(II) с модифицированными редокс -свойствами
