The synthesis, characterization and properties of new organometallic polymers
We have reviewed recent work on highly branched polymers called dendrimers. Two novel block copolymers consisting of organoruthenium dendritic wedges and linear polyethylene glycol blocks have been prepared. These new block copolymers have been characterized by IR, ¹H and ¹³C NMR, microanalysis, as …

Exploring the Chemistry of Cyclopentadienyl-Cobalt-Cyclobutadiene (CpCoCb) Complexes and Synthesis of Side-Chain CpCoCb Polymers
Synthetic metallopolymers have acquired ample attention recently due to their potential applications as precursors to functional soft materials. Organometallic polymers combine the best of both organic and inorganic polymers. Polyferrocenes comprise the major portion of organometallic polymers. …

CERBERUS-TYPE TRISANIONIC TRISNHC AND ITS ZWITTERIONIC GOLD AND SILVER COMPLEXES
… utility of this novel triscarbene as a ligand in organometallic chemistry has been proven by the construction of homotrimetallic systems. The resulting zwitterionic metal complexes of type [(MPPh)<sub>3</sub>(NHC)] (M = Au or Ag) have been fully characterized by spectroscopic techniques, as well …

Synthesis and Characterization of some Thallium Salt Complexes
<p>Research into conductive organic and organometallic polymers began in 1977 when Heeger, Macdiarmid, and Shirakawa first doped polyacteylene with Iodine. They found that this doping granted the polymer metallic properties increasing conductivity by 11 orders of magnitude.[1] Unfortunately, …

Understanding the impact of polymer functionalized electrode fabrication and cycling conditions on stability and selective separation of micropollutants
The main focus of this thesis is on selectively separating target contaminants present in an aqueous environment via electrochemically-mediated capture at polymer interfaces in order to improve water security. Heavy metal pollutants such as arsenic have diverse physico-chemical properties which …

Synthesis and Structures of New Three-Dimensional Copper Metal-Organic Frameworks
<p>Metal-organic frameworks (MOFs) are crystalline materials with metal ions covalently bonded to organic ligands. The ligands act as spacers often creating a porous structure with very high pore volume and surface area. MOFs are known for their robust structures, high porosity, and different …
