Abstract

original image

Phenalenyl in action: The cationic state of the phenalenyl system can be used to design Lewis acidic catalysts. The phenalenyl backbone can tune the energy of the lowest unoccupied molecular orbital (LUMO) of the molecule, which in turn controls the catalytic activity in the ring-opening polymerization of cyclic esters (see figure).
