a number of redox-active coordination polymers (cps) or metal-organic frameworks (mofs) have been successfully synthesized using transition metals and bridging ligands. this article aims to deal with gathering the aforementioned disperse issues regarding the electroactive cps. it also goes towards illustrating the effects of various factors on the electrochemical behavior of cps including natur...

A wide range of transition metal imido (TMI) complexes is studied using ab initio molecular orbital (MO) calculations. The main computational point of interest is the further testing of effective core potentials (ECPs) and valence basis sets to allow for the accurate calculation of properties for reasonably sized transition metal complexes. On the chemical side, several results from the study a...

Metal Insulator transition(MIT) is characterized by the conductivity which will be zero in the insulator phase. In this term paper, we focus on Mott insulator, and a simple theoritical way to describe this MIT is the Hubbard Model .Finally, we will look at the experiments of Mott insulator transition .

Even so, extensive research has been carried out on potential eco-toxic effects of particulate and extensively degraded oxo-biodegradable plastics when mixed with soil. Tests included seed germination and plant growth rates, compared with the same soil without degraded plastics [3,4], the effects on macro-organisms (worms, daphnia, etc.) in the soil [4] and on the accumulation of transition met...

Aromaticity is an important concept in chemistry primarily for organic compounds, but it has been extended to compounds containing transition-metal atoms. Recent findings of aromaticity and antiaromaticity in all-metal clusters have stimulated further research in describing the chemical bonding, structures and stability in transition-metal clusters and compounds on the basis of aromaticity and ...

Homogeneous transition metal complex catalysts for organic industrial processes are converted to catalysts which are heterogeneous with respect to the reactants, and which have substantially equal catalytic activity to the homogeneous catalysts. This is done by reacting a normally homogeneous transition metal complex catalyst with a metal bridging ligand which substantially duplicates the ligan...

ganic chemistry. In particular, they play an important role in carbon–carbon bond formation. A metalacycle, i.e., a ring compound containing a transition metal, is a useful intermediate in synthetic organic chemistry. Oxidative cyclization of unsaturated hydrocarbons, such as alkene, alkyne, carbonyl compounds, or nitrile, using a low-valent transition metal is a useful reaction for synthesis o...

calixarenes are a readily available and important class of macrocycles in supramolecularchemistry. calixarenes have generated considerable interest due to their basket shaped structureand as useful building blocks to synthesize selective receptors for the guest species, notably alkali,alkaline earth, lanthanide and transition metal cations. in this work studied on the complexingproperties of a ...

In the last few years, transition metal-mediated reactions have joined the toolbox of chemists working in the field of fluorination for Life-Science oriented research. The successful execution of transition metal-catalyzed carbon-fluorine bond formation has become a landmark achievement in fluorine chemistry. This rapidly growing research field has been the subject of some excellent reviews. Ou...
