A chiral copper( I )‐complexed [2]catenane consisting of two interlocking 38‐membered rings, each ring incorporating a 2,9‐diphenyl‐1,10‐phenanthroline (dpp) and an ( S )‐1,1′‐binaphthyl group, has been prepared by means of a transition metal template strategy. Demetalation afforded the corresponding free chiral [2]catenane. The coordination polyhedron of the Cu(dpp) 2 core in this chiral copper( I )‐complexed [2]catenane reflects the distortion of the chiral 1,1′‐binaphthyl units, as evidenced by the circular dichroism (CD) measurements. Emission measurements demonstrated that in the two‐chromophore compounds ( S )‐ 6 and ( S , S )‐ 9 , efficient energy transfer between the 1,1′‐binaphthyl component and the dpp unit takes place in solution at room temperature.
