U.S.-Korea Cooperative Science: Magnetic Studies of Metalloporphyrin-based Magnets

9910383米勒拟议的研究扩大和延长了国际科学基金会目前的国家科学基金奖，CHE-9730984专门旨在探索国际科学基金会团队发现的一类有机基磁体，即通过与韩国光州国立大学的金金原教授合作，研究由[MPOR]+[TCNE]-.S(POR=卟啉；S=溶剂)(TCNE=四氰乙烯)组成的可溶性配位聚合物磁体。这项合作将利用Kim教授团队的合成专业知识来制备二茂铁基取代的卟啉，并开发方法来制备自组装单分子膜，并从单层表面制备作为受控薄膜的[MPOR]+[TCNE]-.S磁体。合作研究的总体目标是：(1)了解控制这些可溶聚合物磁体的磁性行为的基础科学；(2)识别新的现象；以及(3)制造具有可控和高老化温度、T_c和矫顽场的对象。该项目将与韩国光州国立大学的Kim教授合作进行。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。韩国的参与得到了韩国科学与工程基金会(KOSEF)的支持。

9910383MillerThe proposed research expands and extends the PI's current NSF award, CHE-9730984 aimed specifically at exploring one class of organic-based magnets that the PI's group discovered, namely, the study of soluble, coordination polymeric magnets comprised of [Mpor]+[TCNE]-.S (por = porphyrin; S = solvent) (TCNE = tetracyanoethylene) via a collaboration with Prof. Jinkwon Kim of the Kongju National University in Korea. This collaboration will take advantage of the synthetic expertise of Prof. Kim's group to prepare ferroceneyl substitued porphyrins, and to develop methodologies to fabricate a self assembled monolayer and prepare [Mpor]+[TCNE]-.S magnets as controlled thin films from the monolayer surface. The overall goals of the collaborative research are:(1) understanding the fundamental science that governs the magnetic behavior of these soluble polymeric magnets;(2) identifying new phenomena; and(3) making obms with controllable and high odering temperatures, Tc, and coercive fields.This project will be performed in conjunction with Prof. Kim of the Kongju National University, Korea. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program, which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation is supported by the Korea Science and Engineering Foundation (KOSEF).
