诺奖得主费林加:让年轻人认识科学之美
Huan Qiu Wang Zi Xun· 2025-07-20 12:05
Group 1 - The event "Interdisciplinary Crossing: Space Station for Innovation Principals" was held at the Shanghai Natural History Museum, featuring Nobel Laureate Bernard Feringa as a keynote speaker [1][3] - Feringa emphasized the importance of creativity and imagination among young people to drive innovation and societal development [3][5] - His lecture titled "The Joy of Discovery" highlighted advancements in molecular motors and switches, pointing out the vast possibilities offered by synthetic chemistry in various fields such as pharmaceuticals and displays [3][5] Group 2 - Feringa introduced his new book "Fascinating Chemistry: Molecules in Life," which aims to make complex chemical knowledge accessible and engaging through everyday phenomena [5] - The event was seen as a platform to inspire children's scientific dreams, as noted by Ni Minjing, the director of the Shanghai Science and Technology Museum [5]
新型有机金属化合物挑战“十八电子规则”

Core Insights - The research team has synthesized the first stable ferrocene derivative with 20 electrons, breaking the long-standing "18-electron rule" in organometallic chemistry, which could lead to new possibilities in chemical research and the development of novel catalysts [1][2] Group 1: Breakthrough in Organometallic Chemistry - The "18-electron rule" has been a fundamental principle in the stability of transition metal complexes, indicating that a system is most stable when the sum of the metal center's electron count and the ligand's contribution equals 18 [1] - The newly synthesized ferrocene derivative features a unique bonding between iron and nitrogen atoms, allowing for the presence of two "excess" electrons, which endows the molecule with unconventional redox properties [1] Group 2: Potential Applications - The formation of iron-nitrogen bonds in the new compound provides a richer and more diverse pathway for electron transfer, suggesting potential applications in energy storage and chemical synthesis [2] - Existing ferrocene derivatives are already utilized in various fields, including solar cells, pharmaceuticals, and medical devices, and this breakthrough may not only optimize current applications but also lead to entirely new materials and uses [2]

Core Insights - The integration of artificial intelligence (AI) and automation in synthetic chemistry is seen as the future, enhancing efficiency and reducing reliance on traditional trial-and-error methods [1][3][4] - The vastness of chemical space presents significant challenges for chemists, with the theoretical number of small molecules that can be synthesized reaching 10^60, far exceeding the number of stars in the universe [2][3] - Current methodologies in synthetic chemistry include "top-down" experimental approaches and "bottom-up" theoretical approaches, both facing efficiency and universality challenges, necessitating new tools [3][4] Group 1: Challenges in Synthetic Chemistry - Synthetic chemistry is fundamental for creating materials essential for agriculture, health, and industry, but faces increasing demands for new materials and performance [1][2] - The "top-down" approach relies on chemists' intuition and experience, while the "bottom-up" approach uses computational methods, both of which have limitations in efficiency and applicability [2][3] Group 2: Automation and AI in Research - Automation in laboratories, such as high-throughput technology, has been adopted to enhance efficiency in catalyst development, significantly reducing the time required for experiments [4][5] - The use of automated platforms allows researchers to design and test thousands of catalyst formulations quickly, leading to the discovery of new materials that would take much longer through traditional methods [5][6] Group 3: Future Directions - AI's role in chemistry is currently as a supportive tool rather than a replacement for human intuition, with significant potential for development in interpreting experimental results [6][8] - The concept of "self-driving laboratories" is emerging, where automated systems can analyze results and autonomously design subsequent experiments, creating a rapid iterative cycle of design, execution, and learning [9][10]
