Figure 1. (A) The synthetic route of the metallacycle Cu2(1o)2 and Cu2(2o)2. (B) Crystal structure of (S, S)-Cu2(1o)2. (C) The optical rotary dispersion spectra of 1o with CuOTf·0.5C6H6 (-) and 1c with CuOTf·0.5C6H6 (···). (D) The fatigue-resistant property of the optical rotation of 1o with CuOTf·0.5C6H6 at 450 nm (◆) and 475 nm (■) through altering UV and visible irradiation.
