Rapid Redox Hopping Charge Transfer and Electrochromism in a Multivariate Metal-Organic Framework.

ABSTRACT: Electrochromic materials exploit a change in molecular absorbance after an electrochemical redox event for applications, such as smart glass and segmented displays. Current applications use metal oxides; however, these materials are plagued by slow response times to potential changes. Herein, we investigate a metal-organic framework (MOF) film loaded with a molecular ruthenium redox carrier for its electrochromic capabilities. Upon the application of a potential jump, the native MOF was found to transport charge with an apparent diffusion coefficient, D_app of 8(±3) × 10^-9 cm²/s. That said, only 55% of the redox centers, primarily those at the MOF surface, were converted. Using a multivariate (MTV) approach to incorporate sulfonate groups into the bac
