Chinese scientists have for the first time the molecular energy transfer between "taking pictures"

News Agency in Hefei, March 31 (reporter Wu LAN) 31st learned from ustc, researchers for the first time at the school to achieve coherent Imaging observation of dipolar coupling between molecules, that is, energy transfer between molecules "photo".
31st international authoritative academic journal, the journal nature published the results, and in the "news and views" section to "coupling molecular close-up titled" special report.
People usually think intuitively, energy transfer between molecules like football players pass, by accepting energy transfer to the adjacent molecules, then pass it on. But some of the latest experiments, an injection of energy, may cause adjacent the law has some linkage, or coherent coupling between adjacent molecular dipole. Prior to that, scientific community and the coherence of the molecular dipole coupling and features has been the lack of direct knowledge.
Ustc single molecular sciences team introduced Dong Zhenchao, energy transfer between molecules is an important way of sustaining life and its evolution, and photosynthesis efficient light-harvesting mechanism for understanding the natural world plays a very important role.
The study to provide in-depth understanding of Intermolecular energy transfer with unprecedented spatial information, but also for the development of efficient light-harvesting structures and quantum entanglement of light provides a new way of thinking.
The reviewer in the journal nature says, "this work opens up new ways for studying molecular interactions", "for many fields--from basic research on the interactions between molecules to light-harvesting system and practical applications such as quantum optics, have broad implications and significance. ”

中国科学家首次为分子间能量传递“拍照”

　　中新社合肥3月31日电  (记者 吴兰)记者31日从中国科大获悉，该校科研人员在国际上首次实现分子间相干偶极耦合的成像观察，即为分子间能量传递“拍照”。

　　31日，国际权威学术期刊《自然》杂志发表了这项成果，并在“新闻与观点”栏目中以“耦合分子的特写镜头”为题进行特别报道。

　　人们直觉上通常认为，分子间的能量传递就像足球队员传球一样，由接受能量的分子传送给相邻的另一个分子，然后依次传递下去。但最新的一些实验表明，一份能量的注入，可能会引起相邻分子间有一定规律的联动，或者说相邻分子的偶极之间产生相干耦合。在此之前，科学界对分子偶极耦合的相干性的形式和特性一直缺乏直接的认识。

　　中国科大单分子科学团队董振超介绍，分子间的能量传递是维系生命及其演化的重要方式，对了解自然界中光合作用的高效捕光机制具有非常重要的意义。

　　这项研究为深入理解分子间能量传递提供了前所未有的空间信息，也为研制高效的捕光结构和量子纠缠光源提供了新的思路。

　　《自然》杂志的审稿人认为，“这项工作开辟了研究分子间相互作用的新途径”，“对于许多研究领域——从分子间相互作用的基础研究到捕光体系和量子光学等实际应用，都具有广泛的影响和重要的意义。”
