The book "Chemistry of Nanomolecular Systems" offers a comprehensive examination of molecular electronics, particularly the use of individual molecules. Given the challenges posed by current silicon-based technology, the development of alternative processes is becoming increasingly urgent. This specialized book highlights advancements in research on single molecules and their integration into electrical circuits to develop more powerful and faster processors. The authors Takayoshi Nakamura, Takuya Matsumoto, Hirokazu Tada, and Ken-ichi Sugiura guide readers through the history and current developments in this innovative field, starting from the first concepts of single molecules in the late 1970s to modern techniques of single-molecule manipulation. With 217 pages and numerous illustrations, the book provides both theoretical and practical insights into the chemistry of nanomolecular systems and their application in electronics.
