Synthesis And Solution Chemistry Of An Octabrominated Iron (Iii) Porphyrin For Oxygen-Activation Catalysis, Daniel Mccall Jan 2007

Synthesis And Solution Chemistry Of An Octabrominated Iron (Iii) Porphyrin For Oxygen-Activation Catalysis, Daniel Mccall

The Corinthian

The chemistry of water-soluble cationic porphyrins has been actively pursued in the interest of providing new materials with electronic and magnetic properties suitable for use in optical and memory devices as well as for the fabrication of metallocatalysts for the heterogeneous activation of oxygen. To this end, we have synthesized a new cationic iron(III) porphyrin bearing bromine substituents at the porphyrinic carbons.

Electrochemical studies of the iron(III) complex indicated an increase in oxidation strength by 0.33 V shift to more positive potential for the Fe(IIVII) redox potential compared to the non-brominated iron complex. The synthesis and spectroscopic properties of the …


Sol-Gel Technology In Enhancing The Filtration Of Semi-Volatile Organic Compounds, David T. Nguyen, Jennie Ash, Chastity Ellison Jan 2007

Sol-Gel Technology In Enhancing The Filtration Of Semi-Volatile Organic Compounds, David T. Nguyen, Jennie Ash, Chastity Ellison

The Corinthian

For the past several years, the field of sol-gel technology has undergone remarkable growth in areas ranging from micro-fibers to chemical sensors. Incorporating an organic phase into the colloidal mixture via pre- or post-doping can modify sol-gels, and manipulation of the size of the pores can be used in developing 'eco-friendly' water filters, particularly for filtering semi-volatile organic compounds in water. In this research project, various forms of sol-gels were made to see which is more efficient for certain semi-volatile chemicals that can be found in diverse sources of water. Organically modified silicates and different structurally sound sol-gels were made …
