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.

Aggregation‐Induced Emission: A Rising Star in Chemistry and Materials Science

“…In 1853, G. G. Stokes reported that BaPt(CN) 4 exhibited bright green fluorescence in solid state but its solution looked like "mere water". [9] Unfortunately, the mechanism of this peculiar photoluminescence behavior had not been revealed. In addition to inorganic matters, some organic dyes with enhanced emission in the solid state have also been reported in the late 19th and early 20th centuries.…”
