| Popis: | Coordination polymers (CPs) supporting tunable through-framework conduction and responsive properties are of significant interest for enabling a new generation of active devices. However, such architectures are rare. We report a redox-active CP composed of two-dimensional (2D) lattices of coordinatively bonded Mo2(INA)4 clusters (INA = isonicotinate). The 2D lattices are commensurately stacked and their ordering topology can be synthetically tuned. The material has a hierarchical pore structure (pore sizes distributed between 7 and 33 A) and exhibits unique CO2 adsorption (nominally Type VI) for an isotherm collected at 195 K. Furthermore, cyclic voltammetry and electrokinetic analyses identify a quasi-reversible feature at E1/2 = −1.275 V versus ferrocene/ferrocenium that can be ascribed to the [Mo2(INA)4]0/–1 redox couple, with an associated standard heterogeneous electron transfer rate constant ks = 1.49 s–1. The tunable structure, porosity, and redox activity of our material may render it a promising ... |
