Abstract The photovoltaic properties of quantum dot (QD) sensitized solar cells (QDSCs) depend significantly on the surface modification applied to QDs and nanostructured interface between electrode surface. In development QDSCs with spatially ordered QD arrays, linking molecular ligands (QD-ligands) can lead realization novel QDSCs. ligand shell around mediates electron energy transfer process...

ABSTRACT Ru(II)BT have been synthesized by the reaction between substituted bromobenzal thiosemicarbazones and precursors of ruthenium metal complexes, [RuHCl(CO)(EPh3)3] (where E = P/As). The Ru(II)BT was characterized analytical spectroscopic techniques. It confirms coordination thiosemicarbazone ligands suggest octahedral geometry complexes. is comprised a centre with bidentate ligands. s...

Surface ligands play critical roles in determining the surface properties of metal clusters. However, modulating and controlling structure clusters through surface-capping-agent displacement is challenging. Herein, [Ag14(SPh(CF3)2)12(PPh3)4(DMF)4] (Ag14-DMF; DMF=N,N-dimethylformamide), with weakly coordinated DMF on silver sites, was synthesized by a mixed-ligands strategy. Owing to high reacti...

Cyclopentadienide (Cp) groups are among the most popular ligands in organometallic chemistry. Sterically demanding substitution patterns on Cp ring can have an important effect ligand properties and there many examples of metal complex which only stable isolatable with sterically ligands, carrying alkyl or aryl groups. Among these pentaisopropylcyclopentadienide is bulkiest pentaalkyl derivativ...

The Notch pathway is integrated into numerous developmental processes and therefore is fine-tuned on many levels, including receptor production, endocytosis, and degradation. Notch is further characterized by a twofold relationship with its Delta-Serrate (DSL) ligands, as ligands from opposing cells (trans-ligands) activate Notch, whereas ligands expressed in the same cell (cis-ligands) inhibit...

Epsilon cobalt nanoparticles are underexplored in catalysis due to the fact that they accessible only through wet-chemical approaches, which employ ligands as stabilizing agents. Ligands may play a significant role determining structure and catalytic performances of nanoparticles, complicates their comparison catalysis. Here, we present cinnamaldehyde hydrogenation freestanding few-layer graphe...

We report the facile synthesis of TbIII and EuIII adducts able to elicit circularly polarized luminescence. Both sensitization lanthanide-ion-centered luminescence (i. e. antenna effect) chiral environment around metal ions are brought about by commercially available enantiopure 2,6-bis(oxazolinyl)pyridine ligands (PyBox). This strategy is promising for development a wide range new simple (CPL)...

TCR ligands are complexes of peptides and MHC proteins on the surfaces of APCs. Some of these ligands cause T cell proliferation (agonists), while others block it (antagonists). We compared the acid release, calcium flux, and proliferation response of helper T cells to a variety of ligands. We found that all agonist ligands but not most antagonist ligands trigger acid release, a general indicat...
