The Advanced Materials Program in the Division of Chemistry makes this award to University of Massachusetts Amherst. With the award, Professor Paul Lahti will study the synthesis and characterization of new stable radicals that incorporates hydrogen bonding groups and coordination groups such as carboxylates, pyridines, imidazoles and fluoroarenes. This interdisciplinary research will use organic, physical and inorganic chemistry as well as physics for crystal engineering to induce ferromagnetic spin-spin interactions and alignments. As part of this award, international collaborations will be carried out with University of Zaragoza in Spain and Osaka University in Japan to study molecular magnetism in organic polymers and materials. Training and education of students in organic synthesis and characterization of novel materials for molecular magnetic applications will be greatly enhanced by this award.Hydrogen bonding, partial fluorination, co-crystallization and transition metal complexation will be used in crystal engineering to induce and enhance ferromagnetic spin-spin interactions and alignments. This interdisciplinary study will have a broad impact on different field such as physical and organic chemistry, and solid state physics. These studies will provide information about the higher critical temperatures required for ferromagnetic and ferromagnetic applications. In addition, this award will provide education and training opportunities to graduate and undergraduate students.

化学系的先进材料计划将此奖项授予马萨诸塞州阿默斯特大学。 凭借该奖项，Paul拉赫蒂教授将研究新的稳定基团的合成和表征，这些基团包含氢键基团和配位基团，如羧酸盐，吡啶，咪唑和氟代芳烃。 这项跨学科研究将利用有机、物理和无机化学以及晶体工程物理学来诱导铁磁自旋-自旋相互作用和排列。 作为该奖项的一部分，将与西班牙萨拉戈萨大学和日本大坂大学开展国际合作，研究有机聚合物和材料中的分子磁性。 该奖项将大大加强对学生在分子磁性应用的有机合成和表征方面的培训和教育。氢键，部分结晶，共结晶和过渡金属络合将用于晶体工程，以诱导和增强铁磁自旋-自旋相互作用和排列。这一跨学科的研究将对不同领域产生广泛的影响，如物理和有机化学，以及固态物理。 这些研究将提供铁磁和铁磁应用所需的更高临界温度的信息。此外，该奖项将为研究生和本科生提供教育和培训机会。
