This thesis describes the first and long-sought successful synthesis of a new pyrazole-expanded porphyrin, a higher analog of porphyrin. This "Siamese-Twin Porphyrin" provides two conjoined porphyrin-like coordination spheres, thus being able to accommodate two metal ions within the same ligand. In her thesis, Lina Blusch not only explains the challenging synthesis and characterization of the ligand system, but also its application to the synthesis of homo- and hetero-bimetallic Ni and Cu complexes. She observes interesting metal-metal-interactions in the complexes, that lead to a non-innocent multistep redox chemistry. The ligand system and its complexes show an intriguing twisted geometry, giving rise to helical chirality and other fascinating properties. This study explores the first steps and opens up a new chemistry of expanded porphyrins with the potential to biomimetic applications.
It is often said that life lessons are more often 'caught' then 'taught' and this collection of memoirs reminds parents that our children are always watching, often laughing, and occasionally learning. Written to honor his father Gerald in his eightieth year, this memoir highlights 55 (the 'double-nickle') childhood interactions between the author and his father written during the author's fifty-fifth year. Sometimes funny, often poignant, the reader will likely read and remember stories from their own childhood.
As a child of the period immediately following World War II, the author takes you to his humble beginnings in a rural community in west central Ohio, where life was simple and worries were few. Along the way, the sights and sounds of his boyhood surroundings bubble from his fertile memory. You'll read about the people and events in a village where Main Street was not the main street, and where picture shows, ice cream parlors, and J.C. Penney were among weekend diversions. You'll also learn how the author came to have three sets of grandparents. A recounting of an event that occurred at the county fair gave rise to the book's main title, "A Nickel and a Gallon of Gas." You'll visit a century-old maple tree whose solid roots beside the author's boyhood home grounded it against the storms of time, just as his solid, small town upbringing helped him face the gales of life that were yet to come. If you're of a similar generation, you may pass signposts of your life during this journey into yesterday. At the same time, those accustomed to the modern era may soon learn that life was a little different in those "good old days."
