DyIII- and YbIII -curcuminoid compounds: Original fluorescent single-ion magnet and magnetic near-IR luminescent species

The multifunctional behavior of two mononuclear lanthanide compounds attached to a curcuminoid called 9 Accm has been investigated. The results show that [Dy(9 Accm) 2(NO 3)(dmf) 2] Yb(9 Accm) 3(py)] behaves as a single-ion magnet and that both compounds display luminescent responses and exhibit affinity for graphite surfaces.
