We have synthesized and tested new highly fluorescent metal organic framework (MOF) materials
based on stilbene dicarboxylic acid as a linker. The crystal structure and porosity of the product are
dependent on synthetic conditions and choice of solvent and a low-density cubic form has been
identified by x-ray diffraction. In this work we report experiments demonstrating scintillation
properties of these crystals. Bright proton-induced luminescence with large shifts relative to the
fluorescence excitation spectra were recorded, peaking near 475 nm. Tolerance to fast proton
radiation was evaluated by monitoring this radio-luminescence to absorbed doses of several hundred MRAD.
