Abstract

The first rationalized crown ether–bis(porphyrin) conjugate with a large ring-based conformation flexiblity 1 has been synthesized; the achiral-to-chiral transformation upon complexation with chiral diamines is assisted by K+ accommodated in the crowned moiety, and it is possible to determine the chirality of carboxylates as potassium salts.
