Organic pigments such as indigos, quinacridones, and phthalocyanines are widely produced industrially as colorants for everyday products as various as cosmetics and printing inks. Herein we introduce a general procedure to transform commercially available insoluble microcrystalline pigment powders into colloidal solutions of variously sized and shaped semiconductor micro- and nanocrystals. The ...

In the title compound, [Co(C(5)H(3)N(4)O)(N(3))(H(2)O)](n), the cobalt ion is coordinated by three N atoms of two organic ligands, two N atoms of two azide anions and one water mol-ecule in a distorted octa-hedral geometry. The metal atoms are connected via the ligands into layers, which are further connected by O-H⋯N and O-H⋯O hydrogen bonding.

Many of the desirable properties of metal-organic frameworks (MOFs) can be tuned by chemical functionalization of the organic ligands that connect their metal clusters into multidimensional network solids. When these linker molecules are intrinsically fluorescent, they can pass on this property to the resultant MOF, potentially generating solid-state sensors, as analytes can be bound within the...

The recent thrust in utilizing atomically precise organic ligands protected gold clusters (Au clusters) as photosensitizer coupled with semiconductors for nano-catalysts has led to the claims of improved efficiency in photocatalysis. Nonetheless, the influence of photo-stability of organic ligands protected-Au clusters at the Au/semiconductor interface on the photocatalytic properties remains r...

Abstract Organic Cu-binding ligands have a fundamental influence on Cu distributions in the global ocean and they complex >99% of dissolved seawater. however, represent large diversity compounds with distinct sources, sinks chemical properties. This heterogeneity makes organic ligand pool difficult to study at scale. In this review, we provide an overview that compose marine Cu-ligand pool, ...

Integrating a matched organic chromophore and a Ru(II) complex with optimized tridentate polypyridine ligands instils reversible electronic energy transfer giving an unusually long room temperature luminescence lifetime (42 μs) without compromising the emission quantum yield.

Robust charge-neutral Pt(II) complexes containing dianionic tetradentate bis(N-heterocyclic carbene) ligands exhibit intense blue phosphorescence in fluid solutions and in polymer films, and have been vacuum-deposited as a phosphorescent dopant in organic blue-light-emitting diodes.

A range of anionic metal-organic framework (MOF) materials has been prepared by combination of In(III) with tetracarboxylate isophthalate-based ligands. These materials incorporate organic cations, either H2ppz2+ (ppz = piperazine) or Me2NH2+, that are hydrogen bonded to the pore wall. These cations act as a gate controlling entry of N2 and H2 gas into and out of the porous host. Thus, hysteret...

We report a class of ligands that are candidates to construct metal-organic frameworks with long-range magnetic order between transition metal centres. Direct quantum chemical calculations predict Néel temperatures exceeding 100 K for the case of Mn.

Cu(2)ZnSnS(4) (CZTS) nanocrystals sterically stabilized with oleic acid and oleylamine ligands and dispersed in nonpolar organic liquids have been extracted into, and electrostatically stabilized in, polar liquids by covering their surfaces with S(2-).
