Abstract

Light-induced structural changes in crystals of a luminescent silver(I) complex were evaluated at 100 K via time-resolved laser-pump/X-ray-probe Laue diffraction. Based on theoretical modelling, they are attributed to the S₀ → S₁ LLCT electronic transition. Low-temperature photoluminescence spectroscopy revealed 2-ns-lived emission followed by phosphorescence. Above 200 K, the system becomes majorly TADF-emissive.
