Synthesis and characterization of aluminum oxide based materials - from molecule to device

Creator:: Wang, Wei
Abstract:: A scalable synthesis of the "flat" tridecameric inorganic cluster [Al₁₃(μ₃-OH)₆(μ-OH)₁₈(H₂O)₂₄]¹⁵⁺ has been realized by treating an aqueous aluminum nitrate solution with zinc-metal powder at room temperature. Single crystals and polycrystalline samples are readily obtained in yields exceeding 55% relative to the starting reagent Al(NO₃)₃. Products have been characterized by X-ray...

Investigation of the structural influence on the properties of functional inorganic oxides

Creator:: Laurita-Plankis, Geneva
Abstract:: While properties are extremely important from an application point of view, it is crucial to have a detailed understanding of the underlying structural influence. Once a concrete correlation between the structure and the observed property is established, rational design of novel materials with optimized properties can be realized. These optimized...

Total synthesis of sparteine alkaloids from a common tetraoxobispidine intermediate

Creator:: Melbardis, John
Abstract:: In previous work (Blakemore et al. Org. Lett. 2005, 7, 4721; Heterocycles 2006, 70, 609), successful elaborations of the lupine alkaloids (±)-α-isosparteine (dl-2) and (±)-β-isosparteine (dl-3) were realized from a common tetraoxobispidine precursor, 3,7-diallyl -2,4,6,8-tetraoxo-3,7-diazabicyclo[3.3.1]nonane (93). Herein, the tetraoxobispidine approach to lupine alkaloids was extended to a total synthesis of...
