“…We investigate the complex Re(2,2 0 -bipyridyl-4,4 0 -bisphosphonic acid)(CO) 3 Cl (Fig. 1, ReP-Cl) 20,24,25 anchored on a 200 nm thick mesoporous layer consisting of ZrO 2 nanoparticles (20-40 nm diameter) on a CaF 2 substrate. Synthesis of the rhenium complex was performed according to published procedures.…”

“…Our investigations started by studying different semiconductors as photocatalysts in the metallaphotocatalytic cross‐coupling of methyl 4‐iododbenzoate and 2‐mercaptoethanol in presence of catalytic amounts of NiBr 2 ⋅ 3H 2 O, a bipyridine ligand that is equipped with phosphonic acid groups (dpbpy=[2,2′‐bipyridine]‐4,4′‐diyldiphosphonic acid), and a base (Table 1). Using blue light (440 nm), two carbon nitride materials (CN‐OA‐m [15] and mpg‐CN [16] ), TiO 2 P25, dye‐sensitized TiO 2 P25 (pre‐functionalized with a ruthenium dye that contains a phosphonic acid anchoring group (Ru(bpy) 2 (dpbpy)‐TiO 2 ) [17] ), and CdS resulted in the formation of the desired coupling product (Entry 1–5). Bismuth oxide was unsuitable as photocatalyst (Entry 6–7).…”

Metallaphotocatalytic cross‐coupling reactions are typically carried out by combining homogeneous or heterogeneous photocatalysts with a soluble nickel complex. Previous attempts to realize recyclable catalytic systems use immobilized iridium complexes to harvest light. We present bifunctional materials based on semiconductors for metallaphotocatalytic C−S cross‐coupling reactions that can be reused without losing their catalytic activity. Key to the success is the permanent immobilization of a nickel complex on the surface of a heterogeneous semiconductor through phosphonic acid anchors. The optimized catalyst harvests a broad range of the visible light spectrum and requires a nickel loading of only ∼0.1 mol %.

New Mn(II), Ni(II), Co(II) and Cu(II) complexes of an azo dye ligand based on p-phenylenediamine with 5-nitro-8-hydroxyquinoline were synthesized and characterized using elemental analysis, inductive coupled plasma analysis, molar conductance, powder X-ray diffraction, thermogravimetric analysis, magnetic moment measurements, and infrared, 1 H NMR, electron ionization mass and UV-visible spectral studies. The spectral and analytical data reveal that the azo dye ligand acts as a monobasic bidentate ligand via deprotonated OH and nitrogen atom of the quinoline ring. The data support the formulation of all complexes with a 2:1 ligand-to-metal ratio, except the Mn(II) complex that has a mononuclear formula. All complexes have an octahedral structure. The molar conductance data reveal that all the metal complexes are non-electrolytic in nature. From the X-ray data, the average particle size of the ligand and its complexes is 0.32-0.64 nm. The colour fastness to light, washing, perspiration, sublimation and rubbing of the prepared ligand and its complexes on polyester fabrics and colorimetric properties were measured. The results reveal that the ligand and its complexes have a good to moderate affinity to polyester fibres.
