Scientific seminar “Lanthanide‐based Silsesquioxane: Synthesis, Structure, and Properties”
13 May at 15:00 MSK
We report here the synthesis, structure, luminescence and magnetic properties of new cage-like tetranuclear silsesquioxanes Tb3+, Eu3+, Dy3+. They present an unusual prism-like topology of cage architectures and lanthanide-characteristic emission, which makes them the first luminescent cage-like lanthanide silsesquioxanes. One of the Tb3+-based cages presents a magnetic spin-flip transition. The mixed Y3+/Dy3+ compound displays a field-induced Single Molecule Magnet (SMM) behavior making it the first reported bifunctional magneto-luminescent silsesquioxane.
