A new redox-active ligand, tris(4-(pyridin-4-yl)phenyl)amine (Npy3), has been synthesised, and incorporated into the coordination framework [Cu(Npy3)Cl2]·DMF. The monoradical cation of the ligand is readily accessible, thus enabling chemical oxidation of the framework. The novel Npy3 ligand has significant potential as a structural motif for the development of multifunctional frameworks.
