Executive Committee Meeting

Zoom Meeting

Note: I request that all officers, chairs of standing committees (e.g., commmunications, awards), and chairs of topical groups provide updates in our January agenda, specifically on page 2 and onwards. Please feel free to include flyers, links, and any info about upcoming events as well as robust summaries of recent events and activities. If you need the Executive Board to vote on a motion, the information must be provided in advance through this agenda. Note #1: If you cannot edit the file, please send me your changes and I can make the updates on your behalf, Note #2: If you have no report to make, please include "No updates at this time" in your relevant section.  Please update the agenda by MONDAY 08JAN2024 at the latest.  My hope is this will improve the efficiency of our meetings and help disseminate information amongst NJACS leadership. Let me know if you have any questions, comments, or concerns, and I look forward to seeing you next week. If you did not receive a Zoom invite, then register below and you will receive an email with the Zoom connection. Best, Sandra

NMR Seminar with Rongfeng Zheng

MS Teams

Title: Chalcogenide-Stabilized Metal Nanoclusters: Synthesis, Characterizations, and Applications Abstract: This seminar focuses on the atomically precise gold NPs, or NCs. Au25(SR)18 was selected as a model NC to investigate their magnetic properties, with pentanethiol, hexanethiol and octanethiol used as bonding ligands. Both negatively charged and neutral NCs were synthesized, and 1H/13C NMR were used for detailed structural analysis, as well as surface bonding ligand environment analyses. The anion NC (diamagnetic) and neutral (paramagnetic) NCs are compared and by using the diamagnetic chemical shifts as references, paramagnetic Knight shifts can be calculated. These shifts measure the spin density along the carbon chain of the surface ligand. Temperature dependent NMR was used to study the spin density effect. Density functional theory calculations were used to predict the spin density on Au25(SC8H17)18 and compared with the Knight shifts observed from the experiments. New magnetic properties were observed from the Knight shifts plots. Chalcogenide stabilized NCs, such as with selenolates and tellurolates, have been less investigated, especially their exchange reactions with thiolate. The reaction mechanism, specifically the site preferences and how the mixed ligand layer is distributed on the NCs surface in the exchange reaction, is much less understood. PhSeH and (PhTe)2 were used
