The use of Ï -stacking interactions to control the aggregation of photo-active metal centres is explored through the design of bis(2,2â ²;6â ²,2⠲⠲-terpyridyl) metal complexes functionalised with biphenyl â tailsâ . Arylâ aryl interactions control the aggregation of the metal complexes into polymetallic arrays in the solid state. Cobalt(II), ruthenium(II), nickel(II), copper(II), zinc(II) and cadmium(II) bis-ligand complexes and a mixed ligand ruthenium(II) complex have been structurally characterised. The solid-state structures are dependent on which units dominate the Ï -stacking. For cobalt, ruthenium, nickel and copper, biphenyleneâ biphenylene interactions lead to linear rod-like arrays, while for the group 12 d<sup>10</sup> ions zinc and cadmium, biphenyleneâ pyridyl interactions lead to two-dimensional sheets. The addition of the biphenylene tail has favourable effects on the photophysical-properties of the complexes which exhibit room temperature red (ruthenium) or blue (zinc and cadmium) luminescence, both in solution and the solid state.
