We introduce here a new subclass of copper( i ) hybrid emitters simultaneously containing Cu x I y z − anions and Cu + cations, separated in space by a Janus head ligand. When UV-irradiated at 298 K, these unique "Two-In-One" hybrids exhibit a short-lived green TADF with near-unity quantum yield and a strong solvatochromic effect. Moreover, they manifest a strong radioluminescence upon X-ray irradiation. These findings open up new possibilities for the design of highly performing TADF materials. We present a unique new subclass of Cu( i ) hybrid complexes, showing TADF with near-unity quantum yields as well as unprecedented solvatochromic emission and strong X-ray radioluminescence.
