Organic/inorganic hybrid solar cells have great potentials to revolutionize solar cells, but their use has been limited by inefficient electron/hole transfer due to the presence of long aliphatic ligands and unsatisfying continuous interpenetrating networks. To solve this problem, herein, we have developed a one-pot route for in situ synthesis of poly(3-hexylthiophene) (P3HT)-capped CdSe supers...

In the title complex, [CuCl(2)(C(8)H(6)N(2)O)(2)(H(2)O)(2)], the Cu(II) ion is located on an inversion center and is octahedrally coordinated by two N atoms of the 1H-quinazolin-4-one ligand, two chloride ligands and two aqua ligands. The axial Cu-O distances are significantly longer [2.512 (2) Å], than the Cu-N [2.022 (2) Å] and Cu-Cl [2.3232 (4) Å] distances as a result of Jahn-Teller distort...

Metal organic frameworks (MOFs), an emerging class of crystalline nanoporous materials, have recently caught attention for their unique properties such as high surface area, large pore volume, high uniform and permanent porosity, and ease of chemical tenability to introduce additional physical, chemical, or electrical properties. MOFs constructed from inorganic and organic pieces: metal ions an...

Five novel dumbbell-shaped polyoxometalate (POM)-based inorganic-organic-inorganic molecular hybrids are investigated both in polar solvents and at interfaces for potential amphiphilic properties, which are compared with those of conventional surfactants. These hybrids with the general formula {P(2)V(3)W(15)}(2)-bis(TRIS)-linker are formed by linking two Wells-Dawson-type clusters, [P(2)V(3)W(1...

Organic ligands dominate the speciation of iron in the ocean. Little is known, however, about the chemical composition and distribution of these compounds. Here, we describe a method to detect low concentrations of organic Fe ligands using reverse-phase high-performance liquid chromatography (HPLC) tandem multicollector inductively coupled plasma mass spectrometry. This technique can be used to...

This paper will focus on a novel class of inorganic compounds that we term as molecular mineralst (MMs). MMs are clusters of ceramic fragments encapsulated with organic ligands. These compounds can be crystallized from solution as molecular single crystals and have well-defined crystal structures that can be described with X-ray diffraction methods. Most importantly, the ceramic clusters are pe...

There is an upsurge of interest in the synthesis of coordination polymers in contemporary supramolecular chemistry, as coordination polymerization may lead to materials with controllable functions such as porosity, sensing, nonlinear optical (NLO) activity, and chirality. Crystal engineering based on predesigned organic linkers and metal centers (building blocks) with specific coordination geom...

Identifying potential ligand binding sites on a protein surface is an important first step for targeted structure-based drug discovery. While performing control experiments with Escherichia coli peptide deformylase (PDF), we noted that the organic solvents used to solubilize some ligands perturbed many of the same resonances in PDF as the small molecule inhibitors. To further explore this obser...

We have recently developed a series of arsenic ligands based on practical synthetic strategies. Herein, three kinds bidentate with rigid linkers were selected to construct dinuclear rhombic copper(I) iodide (CuI) complexes, whose structures analyzed by X-ray crystallography. They had sufficient solubility in organic solvents, and it was confirmed that their coordination forms kept the solutions...

In this paper, we show that the ambiphilic properties of some organic ligands in organometallic complexes may be retrieved readily from simple calculations in the framework of conceptual density functional theory (C-DFT): namely, the dual descriptor (DD) and the molecular electrostatic potential (MEP) of the ligands afford a rather straightforward interpretation of experimental trends such as t...
