About the cover – “Cyclic molecules in their many and varied forms have long fascinated chemists and ferrocene is undoubtedly an iconic structure in its own right. Now, a team led by Tim Albrecht and Nicholas Long have made macrocycles built up from directly linked ferrocene units. These nanorings, containing 5, 6, 7 or 9 metal centres, are found to be highly symmetric in solution and exhibit fast intramolecular electron transfer between the redox sites. The X-ray structure of the cyclo[6] compound is shown on the cover.”
