Dinuclear metal complexes: multifunctional properties and applications

Abstract

Dinuclear metal complexes have enabled breakthroughs in OLEDs, photocatalytic water splitting and CO2 reduction, DSPEC, chemosensors, biosensors, PDT and smart materials.

A new covalent organic polymer used to highly selective detection of Fe3+ions

“…Fluorescence quenching % = (1 -I/I0) × 100 %, where I0 is the initial fluorescence intensity in the absence of metal ions, I is the fluorescence intensity in the presence of corresponding analyte [22]. Fig.…”

Recent advances in oligomers/polymers with unconventional chromophores

“…In the past decades, organic photoluminescence (PL) materials have undergone continued experimental and theoretical development owing to their established applications in the fields of optoelectronic devices, chemo-/bio-probes, solar cells, environmental sensors, etc. [1][2][3][4][5][6][7][8][9][10][11] Traditional organic PL materials generally comprise predominantly p-conjugated units, such as phenyl, thiophene, fluorene, and carbazole. [12][13][14][15][16] Although they have been exploited for many years, they still have some inherent disadvantages, including complex multi-step synthetic processes.…”

Molecular and Heterogenized Cp*Ir Water Oxidation Catalysts Bearing Glyphosate and Glyphosine as Ancillary and Anchoring Ligands

“…More recently, inspired by the observation that (a) Cp*Ircomplexes bearing N,O --bidentate ligands are among the most efficient WOCs [26,28,[60][61][62][63] and (b) metal-dinuclearity might impart beneficial properties to WOCs, [31,[64][65][66][67] we decided to synthesize EDTA and EDTMP dinuclear Cp*Ir complexes (Figure 2, Ir-EDTA and Ir-EDTMP; EDTMP = ethylenediamine-N,N,N',N'-tetra(methylene phosphonate)) and the related hybrid materials (Ir-EDTA_ TiO 2 and Ir-EDTMP_TiO 2 ), and test them as WOCs. [35] Both molecular and heterogenized WOCs exhibited remarkable activity; importantly, structural and reactivity studies revealed, not unexpectedly, that IrÀ OP(O)(OH)R bond is significantly weaker than IrÀ OC(O)R one.…”
