sp-Hybridized carbon as a building block in the synthesis of molecules and materials

点击翻译按钮获取中文摘要

This proposal outlines synthetic routes to carbon-rich molecules with defined structure using sp-hybridized carbon as a key building block. These molecules are designed to give answers to both fundamental and applied questions in chemistry, as well as physics and materials science. This program follows a “physical organic chemistry” approach: We examine detailed relationships between chemical structure and molecular reactivity/properties, commonly via thermal analyses, electrochemical methods, X-ray crystallography, as well as NMR, emission, and absorption spectroscopies (EPR, vibrational, and transient absorption spectroscopies are used via collaboration). Often, our molecules are designed to answer specific questions posed by collaborators in, for example, molecular electronics and solar energy capture. The proposed research program relies on four interrelated themes.
