1. Kelley, John J. The Synthesis and Characterization of Imidazolium Lithium Phthalocyanines.

Degree: MS, Chemistry, 2008, Wright State University

A series of 1,3-di-substituted-imidazolium lithium phthalocyanines, in which the substituents on the imidazolium nitrogens were combinations of methyl, ethyl, pentyl, hexyl, isopropyl, adamantyl or 2,4,6-trimethylphenyl groups, was synthesized. The cation exchange of a single lithium ion of dilithium phthalocyanine for a 1,3-disubstituted-imidazolium ion was performed by mixing their salts in common organic solvents under ambient conditions. This afforded a number of imidazolium lithium phthalocyanines in moderate yields. They exhibited poor solubility in most solvents. Their composition and purity were initially verified by 1H and 13C-NMR and elemental analysis. The 1H-NMR spectra also indicated that the imidazolium and lithium phthalocyanine ions are present in a 1:1 ratio. Infrared spectra confirmed the C-C and C-N stretching modes that are characteristic of phthalocyanine and imidazolium aromatic structures. UV-Vis spectra for each compound showed essentially no change in absorption from that of dilithium phthalocyanine, which suggests a lack of influence of the imidazolium ions. Thermal properties of the title compounds were determined through melting points and TGA, in which high melting temperatures (330-370°C) were seen for several complexes and lowered thermal stability was seen for all. The crystal structure of the bis(adamantyl)imidazolium derivative was determined through X-ray diffraction. It was found that water molecules are associated to imidazolium and lithium phthalocyanine ions through hydrogen-bonding, which is possibly the basis for crystallization in imidazolium-lithium-phthalocyanines. Advisors/Committee Members: Feld, William (Advisor).

2. Hart, Morgan M. Cationic Exchange Reactions Involving Dilithium Phthalocyanine.

Degree: MS, Chemistry, 2009, Wright State University

Dilithium phthalocyanine (Li2Pc) consists of an aromatic macrocyclepossessing a doubly negative charge and two Li+ counterions. One Li+ ion is easilydisplaceable while the other remains coordinated to the phthalocyanine ring. Thedisplaceable Li+ cation can be exchanged with other cations, such as a singly chargedtetra-alkyl ammonium cation, by using several variations of a general procedure. It hasbeen demonstrated that tetraalkylammonium lithium phthalocyanines (TAA-LiPcs) canbe successfully and reproducibly synthesized with yields ranging from 54.5% up to64.3%. All TAA-LiPcs demonstrated poor solubilities from approximately <0.2 mg/mLto 5 mg/ml in the solvents tested (with the exception of tetrapropylammonium lithiumphthalocyanine and tetrahexylammonium lithium phthalocyanine). All of the TAA-LiPcssynthesized were dark-purple in color, with the exception of tetraheptylammoniumlithium phthalocyanine and tetraoctylammonium lithium phthalocyanine. These twocompounds were dark –blue in color. Melting points varied greatly from >370.4°C to157.9°C and depended greatly upon the alkyl-chain length of the exchanged cation.

3. Beauchamp, Andrew Michael. The Synthesis of Room-Temperature Ionic Liquids and Their Metathesis Reactions with Dilithium Phthalocyanine.

Degree: MS, Chemistry, 2012, Wright State University

A series of alkoxyalkylammonium salts has been synthesized for use in metathesis reactions with dilithium phthalocyanine. The salts, which were ionic liquids at or near room temperature, were synthesized by a nucleophilic substitution of tris[2-(2-methoxyethoxy)ethyl]amine and iodomethane, iodoethane, bromoethane, 1-bromo-propane, 1-bromo-2-(2-methoxyethoxy)ethane, and [2-[2-(2-methoxyethoxy)ethoxy]-ethoxy] p-toluenesulfonate in yields ranging from 67% - 88%. The methyl, ethyl, propyl and tetra[2-(2-methoxyethoxy)ethyl]ammonium salts were obtained for use in metathesis reactions. The salts were liquid at room temperature, with the exception of tetra[2-(2-methoxyethoxy)ethyl]ammonium bromide which was found to melt at 46° and were thermally stable to approximately 200°. The four salts were used in metathesis reactions with dilithium phthalocyanine to produce an alkoxyalkylammonium cation lithium phthalocyanine anion complex in yields from 43% - 73%. The complex products were found to be thermally stable to approximately 300° with melting temperatures ranging from 118° - 160°. The structures of tris[2-(2-methoxyethoxy)ethyl]methylammonium lithium phthalocyanine, tris[2-(2-methoxyethoxy)ethyl]propylammonium lithium phthalocyanine, and tetra[2-(2-methoxyethoxy)ethyl]ammonium lithium phthalocyanine were determined by single crystal x-ray diffraction experiments.
