尽管有机材料经常被用作半导体,比如有机发光二极管和有机晶体管等,但拥有像金属一样的高导电性的有机材料仍然非常稀少。有机金属研发领域存在的一个问题是,良好的导电性能要求材料具有很高的结晶度,但晶体结构却不利于材料的加工和成型。现在,法国斯特拉斯堡大学的研究团队开发出一类新的有机材料,不仅导电性高,而且非常柔软、有弹性,成功克服了上述难题。发表在《美国化学学会会刊》上的这项最新研究称,当使用光脉冲照射时,该材料能够重组其分子以纠正结构缺陷,因此,新材料可以组装为低结晶度结构,然后通过一个光脉冲转换成为具有高导电性的材料。
Although organic materials are often used as semiconductors, such as organic light-emitting diodes and organic transistors, organic materials possessing metal-like high conductivity are still scarce. One of the problems in the field of organometallic research and development is that good conductivity requires high crystallinity of the material, but the crystal structure is not conducive to material processing and molding. Now, the research team at the University of Strasbourg, France, has developed a new class of organic materials that not only offers high conductivity, but also is very soft and flexible, successfully overcoming the above challenges. The latest study, published in the Journal of the American Chemical Society, said that when using pulsed light, the material was able to reorganize its molecules to correct structural defects so the new material could be assembled into a low-crystallinity structure and then passed through one Light pulses are converted into materials with high electrical conductivity.
