Tuning the optical and luminescent properties of materials is of great interest for a range of applications (e.g. sensing and optoelectronics). Miguel Soto, a post-doc in the MacLachlan group, recently discovered how simple solvent molecules can get the job done. Dr. Soto’s paper was recently published in Angew. Chem. Int. Ed. In their report, they explain how solvents can switch the color and luminescence of a platinum(II) complex. In the solid state, this species appears either yellow or orange, depending on the solvent molecules within the powder; in solution, the same complex can emit...
