Summary:Despite dramatic advances in the template-directed synthesis of archetypal [2]rotaxanes, higher order rotaxanes with multiple molecular components (rings or dumbbells) are relatively daunting subjects owing to their synthetic challenges. With unique interlocked architectures, higher order rotaxanes have found applications in artificial molecular machines. In this feature article, we will focus on the recent advances in higher order rotaxanes with well-defined structures. Different types of rotaxane architectures will be described, and their synthetic approaches will be highlighted. Moreover, the stimuli-responsive molecular motion with increasing complexity in these diverse architectures will also be discussed. Recent advances in various types of higher order rotaxanes with precisely controlled architectures are summarized in this feature article.
Bibliography:He-Ye Zhou received his BS degree from Xiangtan University. In 2016, he joined the laboratory of Prof. Chuan-Feng Chen at the Institute of Chemistry, Chinese Academy of Sciences (ICCAS) to pursue his PhD in chemistry. His current research interest is the construction and applications of mechanically interlocked molecules based on triptycene-derived macrocyclic hosts.
Qian-Shou Zong got his PhD from ICCAS under the supervision of Prof. Chuan-Feng Chen in 2006. Since 2009, he has been working as an associate professor at the College of Biological, Chemical Sciences and Engineering, Jiaxing University. In 2019, he joined Prof. Chen's group as a visiting scientist at ICCAS. His current research interests are supramolecular chemistry based on new macrocyclic hosts, and design and synthesis of organic drugs.
Chuan-Feng Chen has been working as a full professor of organic chemistry at the Institute of Chemistry, Chinese Academy of Sciences since 2001. His current research interests include supramolecular chemistry based on synthetic macrocyclic hosts (helic[n]arenes, pagoda[n]arenes), molecular machines and stimulus responsive supramolecular materials, optoelectronic materials and devices, and helicene chemistry.
Ying Han received her BS from Capital Normal University (CNU) in 2007, MS degree from CNU in 2010 under the guidance of Prof. Sheng-Li Cao, and PhD in 2013 from ICCAS under the guidance of Prof. Chuan-Feng Chen. She is now working as an associate professor at ICCAS. Her current research interests are supramolecular chemistry based on new synthetic macrocyclic hosts and molecular machines.
