Cover Feature: A Rotaxane Scaffold for the Construction of Multiporphyrinic Light-Harvesting Devices (Chem. Eur. J. 1/2018)

An electro- and photo-active rotaxane incorporating ten peripheral Zn(II)-porphyrin moieties and a free-base porphyrin stopper has been prepared. Electrochemical measurements revealed that this compound is capable of mimicking the blooming of a flower. On the other hand, steady state investigations have shown that the multi-porphyrinic rotaxane is a light-harvesting device mimicking the antennae of the natural photosynthetic system.
