(Cu→BINAP) CT (CT = charge transfer) equilibrium. Centimeter-sized monoliths and thin films can be fabricated by molding and thermal annealing, highlighting their excellent processability. Moreover, the glasses can be recrystallized by solvent vapor treatment, which triggers distinct changes in luminescent properties. These results establish BINAP-based copper(I) cyanide complexes as a versatile platform for the design of CPL-active metal-organic glasses and point to their promise in optoelectronic applications.
