ABSTRAKT

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 (see figure).
