Autoluminescent Metal-Organic Frameworks (Mofs): Self-Photoemission Of A Highly Stable Thorium Mof

A novel thorium(IV) metal-organic framework (MOF), Th(2,6-naphtalenedicarboxylate)(2), has been synthesized via solvothermal reaction of thorium nitrate and 2,6-naphtalendicarboxilyc acid. This compound shows a new structural arrangement with an interesting topology and an excellent thermal resistance, as the framework is stable in air up to 450 degrees C. Most notably, this MOF, combining the radioactivity of its metal center and the scintillation property of the ligand, has been proven capable of spontaneous photon emission.
