摘要：

We report here the synthesis, structure, luminescence, and magnetic properties of three new cage-like tetranuclear silsesquioxanes (Et4N)(2)[(PhSiO1..5)(8)(Y0.75Dy0.25O1.5)(4)(O)(NO2.5)(6)(EtOH)(2)(MeCN)(2)] and (Cat)(2)[(PhSiO1.5)(8)(DyO1.5)(4)(O)(NO2.5)(6)(EtOH)(2)(MeCN)(2)] (Cat=Et4N or Ph4P). They present a characteristic green-yellow emission. The Y3+/Dy3+ compound displays in addition a field-induced Single Molecule Magnet (SMM) behavior making it the first reported bifunctional magneto-luminescent silsesquioxane.
