Comparative Study of Optical Properties and X-ray Induced Luminescence of Octahedral Molybdenum and Tungsten Cluster Complexes

Abstract

Octahedral metal cluster complexes have high potential for biomedical applications. In order to evaluate, the benefit of these moieties for combined CT/X-ray luminescence computed tomography, this paper compares the photoluminescence, radiodensity and X-ray induced luminescence properties of eight related octahedral molybdenum and tungsten cluster complexes [{M6I8}L6]n, (where M is Mo or W and L is I–, NO3–, OTs– or OH–/H2O). The article demonstrates that despite the fact molybdenum cluster complexes are the better photoluminescence emitters, tungsten cluster complexes, in particular (Bu4N)2[{W6I8}I6], demonstrate significantly higher X-ray induced luminescence due to the combination of relatively good photoluminescence properties and high X-ray attenuation. Additionally, photo-degradation of [{M6I8}(NO3)6]2– was evaluated.
