A X-ray Excitable Vibrational AIE System Based on Platinum (II) Salts

Abstract

Aggregation-induced emission luminogen excited by X-ray is highly advantageous for imaging and diagnosis but has not been achieved. Herein, we demonstrated BaPt(CN)4 as the first inorganic salt based AIE system which can be excited by X-ray. The AIE mechanism of BaPt(CN)4 is studied and the X-ray luminescence of BaPt(CN)4 is tested.understanding the unconventional clusteroluminescence of some non-conjugated luminescent system. More importantly, we found BaPt(CN)4 can be excited by X-ray, which fundamentally is highly significant since it can overcome the excitation limitation resulted auto-fluorescence and poor tissues penetration depth of AIEgens. To the best of our knowledge, this is the first reported AIEgen which could be excited by X-ray. The current work possibly opens a new door for AIE research.
