Abstract:
The reactions of indium trimethyl with the substituted pyrroles HNC4H2Me2-2,5 and HNC4Me4-2,3,4,5 (Me = CH3) yield the solid, high melting dimethylindium azolides Me2In—NC4H2Me2-2,5 and Me2In—NC4Me4, respectively. Colorless and crystalline N-methyl-2-dimethylmetal pyrrolides have been prepared from Me2MCl (M = Al, Ga, In) and lithiated N-methyl pyrrole. All compounds were investigated by MS, NMR (1H and 13C), and vibrational spectra (IR and Raman). The X-ray structure determinations of Me2Ga—C4H3NMe and Me2InNC4Me4 show the triclinic space group P T in both cases, with two formula units per ce

Abstract:
Thiophene (T) and thienothiophene (TT) containing 2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione (DPP) compounds were prepared according to the succinic ester route from the corresponding heterocyclic nitrile precursors. As is typical of most DPP pigments, the new compounds showed high thermal stability and could be obtained in pure form as determined by elemental analysis. The bulk properties and molecular structure of the compounds were further characterized by thin film, powder XRD and solid state CP-MAS 13 C NMR. Density functional theory (DFT) and time-dependent (TD) DFT were employed to stu

Abstract:
1,2,4-Trisubstituted pyrroles were synthesized with an original one-pot domino allylic amination/palladium-catalysed Sonogashira cross-coupling and heterocyclisation process.1H and13C NMR spectra were assigned for twelve new compounds containing different substituents in positions 1 and 2, and a carboxylic acid or ester group in position 4. Each assignment was based on the combination of one, and two-dimensional experiments (APT, COSY, HMBC).

Abstract:
Five major nitrogen chemical structures, present in coals of varying ranks, have been quantitatively determined with the use of nitrogen x-ray absorption near-edge spectroscopy (XANES). Similar studies of the sulfur chemical structures of coals have been performed for the last ten years; nitrogen studies on these fossil-fuel samples have only recently been realized. XANES spectra of coals exhibit several distinguishable resonances which can be correlated with characteristic resonances of particular nitrogen chemical structures, thereby facilitating analysis of these complicated systems.

Abstract:
This thesis deals with the synthesis of novel 1,4-diheteropentalene compounds, especially 4H-thieno[3,2-b]indoles and 1H-benzothieno[3,2-b]pyrrole, and the investigation of their electropolymerization. The aim was to prepare new conducting polymers and to determine how the structure of the monomer influences their electrochemical and spectral properties. The investigation can be subdivided into four parts. 1. In the context of the research on 1,4-diheteropentalenes performed in our laboratory in recent years, I have designed and prepared a series of novel thienoindoles and the isomeric benzoth

Abstract:
In the vast majority of conjugated and aromatic molecules, the outermost occupied orbitals are either of π‎ character or non-bonding lone pairs belonging to heteroatoms. These are the orbitals from which double ionisation gives rise to most of the distinct bands that can be discerned in their spectra. Double photoionisation spectra of ethylene, butadiene, pyrrole, furan, thiophene, benzene, hexafluorobenzene, toluene, pyridine, pyrazine, pyrimidine, pyridazine, naphthalene, azulene, quinoline, biphenyl, TDME, iron pentacarbonyl, ferrocene, and TMPPD are presented with analysis where possible.
