Self assembly of a diphenanthrolinylpyrene-bridged CuI trimer

The ligand 1,8-di(1,10-phenanthrolin-2-yl)pyrene has been prepared and complexed with CuI such that three ligands bridge a triangular arrangement of three metals resulting in a symmetrical helical assembly with each pyrene layered between two phenanthrolines at optimum π-stacking distance.
