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.
Most of the poetry in this book I did in a writing group at Folk Time, a program that helps people recover from mental illness. I write for fun but also as a kind of therapy. How it all happens I don't really know. But I deal with things that trouble, intrigue, confuse, and please most of us: Friends, family, parents, pets, love, loneliness, sex, school, and books. My favorite poets are James Joyce, W.H. Auden, Emily of course, and Ginsberg. Joyce wrote better novels, but I like his poems. Sylvia Plath I can't comprehend except in small doses.
