Carving Out Pores in Redox‐Active One‐Dimensional Coordination Polymers
Abstract
Reduction of the insulating one‐dimensional coordination polymer [Cu(abpy)PF6]n, 1 a(PF6), (abpy=2,2′‐azobispyridine) yields the conductive, porous polymer [Cu(abpy)]n, 2 a. Pressed pellets of neutral 2 a exhibit a conductivity of 0.093 S cm−1 at room temperature and a Brunauer–Emmett–Teller (BET) surface area of 56 m2 g−1. Fine powders of 2 a have a BET surface area of 90 m2 g−1. Cyclic voltammetry shows that the reduction of 1 a(PF6) to 2 a is quasi‐reversible, indicative of facile charge transfer through the bulk material. The BET surface area of the reduced polymer 2 can be controlled by changing the size of the counteranion X in the cationic [Cu(abpy)X]n. Reduction of [Cu(abpy)X]n with X=Br (2 b) or BArF (2 c; BArF=tetrakis(3,5‐bis(trifluoromethyl)phenyl)), affords [Cu(abpy)]n polymers with surface areas of 60 and 200 m2 g−1, respectively.
