Abstract
We present an efficient strategy for obtaining red-emissive molecular nanomagnets by exploring a heterometallic approach. We report the {[DyIII(4-pyridone)5]2[RuII(CN)2(phen)2]2}·(CF3SO3)6·2MeOH (phen = 1,10-phenanthroline) compound composed of exchange-coupled {DyIII2} single-molecule magnets functionalized by Ru(II)-cyanido units. The latter makes the resulting {DyIII2RuII2}6+ cations a unique example of a soluble lanthanide SMM exhibiting red charge-transfer photoluminescence in the solution and solid state, well enhanced when compared with the cyanido precursor.
