  • Application of Metallocenes for the Synthesis of Multiwalled Carbon Nanotubes
    APPLICATION OF METALLOCENES FOR THE SYNTHESIS OF MULTIWALLED CARBON NANOTUBES by Nonjabulo Philile Dominica Ngidi Submitted in fulfilment of the academic requirement for the degree of Master of Science in the School of Chemistry and Physics University of KwaZulu-Natal, Durban, Westville campus February 2016 ABSTRACT Multiwalled carbon nanotubes (MWCNTs) are carbon materials which have one-dimensional structure. They possess unique properties such as semi-conductor and high tensile strength that allow them to be widely used in many applications. MWCNTs and other shaped carbon nanomaterials (SCNMs) were synthesized by chemical vapour deposition (CVD) method. Three factors that affect the morphology, thermal, chemical, mechanical and electrical properties of SCNMs were investigated. The parameters are: carbon source, catalyst (metallocenes), and growth temperature. Two different carbon sources were studied for the synthesis of MWCNTs i.e., toluene and acetonitrile (also used as a nitrogen source). The metallocenes: nickelocene, cobaltocene and ruthenocene were used as catalysts (2.5 wt.%) while ferrocene was employed as control. These metallocenes were investigated because they have similar structure as ferrocene, a well-known catalyst for the synthesis of SCNMs. The synthesis was carried out at five different growth temperatures, 800, 850, 900, 950 and 1000 °C. As-synthesized MWCNTs and other SCNMs were further purified, in order to remove amorphous carbon and this was performed by testing different methods of purification. The effective method for purification of MWCNTs was method 2 which involved refluxing for 24 hours. It was chosen to be the best method because it produced purer MWCNTs as compared to other methods which caused damage to the MWCNTs.

    RESEARCH ACTIVITIES Visiting Professors Visiting Professor KITAGAWA, Hiroshi (from Kyushu University) Creation of Novel Functional Nano Materials Based on Proton-Coupled Electronic Properties Dynamics of molecules and ions in “coordination nano-space” are acted by characteristic nano-fields such as intermolecular interaction, coulomb interaction, catalytic action, etc. This project is to reveal a basic principle of an unusual nano-field acting on coordination space, and to create the nano space where the energy conversions can be easily operated. In particular, we aim at the construction of coordination nano space system which is able to control a series of energy operations such as generation, separation, storage, material conversion of an energy molecule H2, or electron/ion transport. In this year, we have explored a novel hydrogen-energy functional coordination nano-space by using proton-coupled redox and electron-proton interaction. In the present project, we will create new 1) hydrogen- storage nano-materials, 2) highly proton-conductive coordinatiom polymers, 3) highly electron-proton conductive matrerials, etc. Visiting Associate Professor KANAMORI-KATAYAMA, Mutsumi (from RIKEN) Development of the Assay System for Protein-RNA Interactions Recently, it has been cleared that a large amount of non-coding RNA (ncRNA) existed in mammalian cells. Though some ncRNAs are analyzed and cleared to have important functions, what most ncRNAs do is largely unknown. These ncRNAs are thought to function with Protein, RNA or DNA rather than by themselves. Therefore, it is thought that the information of interactions will play an important role to annotate the function of ncRNAs. So, we focused on the protein-RNA interaction (PRI), and have been developing the assay system to obtain PRI information efficiently.

  • Metalation Studies on Titanocene Dithiolates
    inorganics Article Metalation Studies on Titanocene Dithiolates Tilmann G. Kießling and Karlheinz Sünkel * ID Department of Chemistry, Ludwig-Maximilians University Munich, 81377 Munich, Germany; [email protected] * Correspondence: [email protected]; Tel.: +49-89-2180-77773 Received: 18 July 2018; Accepted: 22 August 2018; Published: 24 August 2018 Abstract: Titanocene bis-arylthiolates [(C5H4X)(C5H4Y)Ti(SC6H4R)2] (X,Y = H, Cl; R = H, Me) can be prepared from the corresponding titanocene dichlorides by reacting with the thiols in the presence of DABCO as a base. They react with n-butyl lithium to give unstable Ti(III) radical anions. While the unsubstituted thiolates (X = Y = R = H) react with lithium Di-isopropylamide by decomposing to dimeric fulvalene-bridged and thiolate-bridged Ti(III) compounds, the ring-chlorinated compounds can be deprotonated with LDA and give appropriate electrophiles di-substituted and tri-substituted titanocene dithiolates. Keywords: titanocene thiolates; metalation; chlorocyclopentadienyl ligands 1. Introduction Titanocene compounds, i.e., compounds of the type “Cp2TiXn” where “Cp” stands for a substituted or unsubstituted cyclopentadienyl ligand and “X” for any anionic or neutral ligand and n = 0–2 are arguably the second-most studied metallocenes after ferrocene. Soon after the first synthesis of (C5H5)2TiCl2 in 1954 [1], its potential for acting as a polymerization catalyst when combined with certain aluminum compounds was discovered [2]. Further studies showed that a judicious choice of substituents on the cyclopentadienyl ring had a great influence on the stereochemistry of the produced polymers, which gave rise to an enormous number of publications and also many review articles [3–8].

A Thesis submitted by JON ARMISTICE McCLEVERTY, B.Sc. for the Degree of Doctor of Philosophy of the University of London. Royal College of Science. May 1963. This Thesis I dedicate to DIANNE. Her love and understanding is a continual inspiration. kit CHAPTER II ic-CYCLOPENTADIENYL METAL HYDRIDES THE DI-n-CYCLOPENTADIENYL HYDRIDES OF TANTALUM MOLYBDENUM. AND TUNGSTEN. The hydride complexes are prepared in high yields by the inter- action of the anhydrous metal chlorides (Noel" 1C16, or TaC15) with a solution of sodium cyclopentadienide in tetrahydrofuran containing an excess of sodium borohydride. Without addition of borohydride to the sodium cyclopentadienide solution only low yields of the hydrides can be obtained since the hydriue ion required must come from the solvent or from traces of excess of cyclopentadiene or cyclopentene present in the reaction mixture. The tantalum hydride, (n-C5H5)2TaH3, is a white crystalline compound which is sensitive to air; the molybdenum and tungsten hydrides, (n-05H5)2MH2, form yellow crystals, the former being more sensitive to air than the latter, which can be handled briefly in air. The tantalum compound is sparingly soluble in light petroleum but it is moderately soluble in benzene; the other hydrides are soluble in light petroleum as well as in other common solvents. Solutions of all three compounds decompose rapidly wren exposed to air. The compounds are soluble in halogenated solvents and in carbon disulphide but react with them quite rapidly, the order of reactivity being Ta Mo ACKNOWLEDGMENTS I would like to express my deep gratitude to Professor G.

  • AROMATIC HYDROCARBONS: Part I
    AROMATIC HYDROCARBONS: Part I DR SUNIL K. SINGH Assistant Professor in Chemistry SK SINGH, KMC Concept of Aromaticity Aromatic compounds apparently contain alternate double and single bonds in a cyclic structure and resemble benzene in chemical behaviour. They undergo substitution rather than addition reactions. This characteristic behaviour is known as aromaticity. Addition reaction: Substitution reaction: Br Br 2 H E CCl + 4 Br E + H+ Br2 No Reaction SK SINGH, KMC CCl4 Following are the main criteria of aromaticity: Chemical behaviour: electrophilic aromatic substitution.

Smaller the heat of hydrogenation Magnetic: "ring current" effects. more is the stability. Benzene is ~36 Kcal/mole more stable than the 1,3,5- • anomalous chemical shifts in NMR. hexatriene. • large magnetic anisotropies • high diamagnetic susceptibility. SK SINGH, KMC Huckel’s Rule and aromaticity A molecule is aromatic if all the following conditions are fulfilled: It is cyclic, planar and it has continuous delocalization of p electrons (electrons in p orbitals) with or without the participation of lone pair(s)/ -ve charge/ +ve charge. Huckel’s rule: The delocalised p-electron system must contain a total of (4n+2)p electrons, where n is a whole number (i.e., n = 0,1,2,3,………). Note that the p-orbitals in which the electrons are delocalizing must be parallel to each other so that a continuous overlap of electrons is possible along the ring.
