AbstractA 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.
