COVER STORY Progress in Macrocycles |
| More than half a century has passed since the birth of a new class of simple artificial cyclic molecules called “Crown Ethers” in 1967, which won the Nobel Prize in Chemistry 1987 for their beautiful structures and intriguing host-guest functions. Also, Crown Ethers received the same prize again in 2016 for the development of molecular machines. Cyclic molecules and supramolecules including Crown Ethers have a major impact on the world of chemistry. Even in the 2020s, state-of-the-art research on topological complexity, unique optoelectronic functions of p-conjugated macrocycles, giant cyclic complexes, and cyclic architectures such as polycatenanes based on molecular assemblies have been reported and their development of progress and diversity is unstoppable. In this special issue, we would like to introduce a wide variety of cutting-edge research on such cyclic molecules and supramolecules. Editors: ISODA, ISHIWARI, IDA, and NISHINA |
