中文摘要
这项工作将完成被设计为铁磁有机金属(FOM)的分子前体的分子的开发。中性供体预期为三亚甲基甲烷,并且一旦以固态掺入叠层中就保持该特性。HTTM和TDMT的合成前体也将被转移到制备具有硫外围的quinodimethanoid供体;后者类似于bisethylenedithio tetrathiafulvalene,预计将产生有机superocinductors。本文将继续研究以多氰基乙烯基取代苯为基础的新型电子受体的物理性质,并合成了一种三方九氰基-1,3,5-三乙烯基苯。TTF和ET的氧类似物的合成以及quinodimethanoid供体的建议,以测试这些较轻的类似物是否会表现出更高的超导体转变温度在其盐与各种阴离子。一旦准备好,固体将使用实验凝聚态物理学的最新发展来确定其物理性质。
英文摘要
This work will complete the development of molecules which are designed to be molecular precursors to ferromagnetic organic metals (FOM). The neutral donors are expected to be trimethylene methanes and to retain this character once incorporated into stacks in the solid state. Synthetic precursors to HTTM and TDMT will also be diverted to prepare quinodimethanoid donors with a sulfur periphery; the latter, in analogy to bisethylenedithio tetrathiafulvalene, are expected to give rise to organic superocnductors. Studies on the physical properties of new electron acceptors based on multi- tricyanovinyl substituted benzenes will be continued and a trigonal, nonacyano-1,3,5-trivinylbenzene. Syntheses of oxygen analogs of TTF and ET as well as a quinodimethanoid donor are proposed in order to test if these lighter analogs will exhibit higher superconductor transition temperatures in their salts with various anions. Once prepared the solids will have their physical properties determined using the latest developments in experimental condensed matter physics.
