New Conductive and Magnetic Materials

本研究致力于基于金属-有机络合物的新型结晶和聚合物、导电和磁性材料的合成和表征。讨论了量子效应对分子金属导电性的影响问题，分子金属是准一维的，但在温度降至零时仍保持高导电性。将制备新的合金来研究一维的近藤效应，并研究由间接载流子介导的局域力矩之间的耦合引起的低温凝聚。探讨了新材料的自旋耦合机制和磁性有序的表征。此外，还制备了最终适合于开发多金属分子络合物和用作导体和磁体的带状和片状聚合物的新的卟嗪-硫醇酸盐。

This research is concerned with the synthesis and characterization of novel crystalline and polymeric, conductive and magnetic materials that are based on metal-organic complexes. The question of quantum effects on electrical conductivity in molecular metals that are quasi 1-D, yet remain highly conductive as temperature goes to zero, is addressed. New alloys will be prepared to study the Kondo effect in 1-dimension, and to examine low-temperature condensation that arises from indirect carrier-mediated coupling between the localized moments. Mechanism of spin coupling and characterization of magnetic ordering in new materials also are explored. Further, new porphyrazine-thiolates are prepared that are eventually suitable for the development of multimetal molecular complexes and ribbon and sheet polymer for use as conductors and magnets.
