A series of inorganic―organic hybrid compounds were analyzed by using X-ray crystallographic techniques to study the secondary interactions in cadmium bromide based hybrid materials. The phenomenon of metallophilic interactions with minimum Cd...Cd distance [3.962(1), 3.389(3) and 3.924(1) Å] has been observed in Cd2, Cd7 and Cd11 compounds whereas the metallophilicity is missing in other compo...
We describe a new supramolecular approach combining host-guest and electrostatic interactions to design hybrid materials containing polyanionic bulky inorganic compounds and showing liquid crystalline properties.
Three thorium(iv)-based metal-organic hybrid compounds with 2D layered and 3D framework structures exhibiting graphene-like (6,3) sheet topologies were prepared with linkers with threefold symmetry. These compounds contain rare and relatively anisotropic coordination environments for low-valent actinides that are similar to those often observed for high-valent actinide ions.
A novel method combining elemental sulfur and selenium was developed, yielding crystalline sulfur-selenium compounds. The compounds were melted, and an organic comonomer added. Once the organic comonomer was consumed, the viscous compound was vitrified and allowed to cool yielding organic-inorganic hybrid polymers that are termed Organically Modified Chalcogenide (ORMOCHALC) polymers.
A structure-activity relationship (SAR) study was carried out to identify novel, small molecular weight compounds which induce readthrough of premature termination codons. In particular, analogs of RTC13, 1, were evaluated. In addition, hypothesizing that these compounds exhibit their activity by binding to the ribosome, we prepared the hybrid analogs 13 containing pyrimidine bases and these al...
Three hybrid compounds have been synthesized through hydrothermal reactions of UO(2)(NO(3))(2)·6H(2)O with 4-halobenzoic acid (X = Cl, Br, I). The formation of these compounds utilizes a composite synthesis methodology that explicitly employs aspects of both coordination chemistry and supramolecular chemistry (namely halogen···halogen interactions).
Histone deacetylase inhibitors (HDACIs) can disrupt the viability of prostate cancer (PCa) cells through modulation of the cytosolic androgen receptor (AR) chaperone protein heat shock protein 90 (HSP90). However, toxicities associated with their pleiotropic effects could contribute to the ineffectiveness of HDACIs in PCa treatment. We designed hybrid molecules containing partial chemical scaff...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
in this study, the effects of different types of hand plucking were studied on green leaf yield and black tea quality. bud and a leaf, bud and two leaves, bud and three leaves and bud and four leaves were the types of hand plucking. plucking was down on chine’s hybrid tea and clone 100 in fuman tea research station. shoots were plucked in flashing period regularly during three years. green leaf...
New hybrid organic-inorganic boron compounds using an imidazole core have been readily synthesized by a two-step procedure from commercially available simple starting materials. All boron compounds were fully characterized by multinuclear NMR spectroscopy, LC-MS, thermogravimetric analysis, cyclic voltammetry and single crystal X-ray diffraction analysis (for & ). The photoluminescence measurem...
