Assembly of a Heterotrimetallic Zn2Dy2Ir Pentanuclear Complex toward Multifunctional Molecular Materials
Rational selection of metal ions and organic ligands to synthesize metal–organic complexes (MOCs) is necessary for constructing multifunctional materials. Herein, we have obtained a novel heterotrimetallic Zn2Dy2Ir pentanuclear MOC by the assembly of DyIII, luminescent ZnII(valpn), and [IrIII(H2L)(...

Summary: | Rational selection of metal ions and organic ligands to synthesize metal–organic complexes (MOCs) is necessary for constructing multifunctional materials. Herein, we have obtained a novel heterotrimetallic Zn2Dy2Ir pentanuclear MOC by the assembly of DyIII, luminescent ZnII(valpn), and [IrIII(H2L)(ppy)2]Cl metalloligands (Hppy = 2-phenylpyridine, H2L = 2,2′-bipyridine-5,5′-di-p-benzoic acid). Single-crystal structural analysis shows that the central [IrIII(L)(ppy)2]− bridges two ZnDy moieties using two carboxylates of L2–. Measurements of organic light-emitting diodes (OLEDs) show that the maximum luminance is 284.2 cd/m2 and the turn-on voltage is 6 V. Magnetic studies reveal that Zn2Dy2Ir is a field-induced single-molecule magnet (SMM) with an energy barrier of 19.1(2) K under a 2 kOe dc field. Zn2Dy2Ir shows luminescence sensing with a quenching efficiency of up to 99.0% for 2,4,6-trinitrophenol (TNP). |
