three types of pyrene-containing phenylpyridine ligands in trimethyl phosphate. The systems include complexes 10 and 12, in which the pyrene ring is cyclometalated by iridium; complex 19, in which the pyrene ring is attached to a pyridine moiety; and complex 32, in which the pyrene is attached to a cyclometalated phenyl moiety. In the solid state, complexes 12 and 19 exhibit π-stacking arrangements through
