| Research Abstract |
A molecular system that allows strategic helicity inversion based on molecular machine mechanism was developed. A single-helical metal complex bearing two crown ether moieties was synthesized. Upon interaction with alkanediammonium salts with different chain lengths, the distance between the two crown ether moieties was altered. Associated with the structural change, inversion of the helical handedness of the metal complex took place (right-handed with shorter guests; left-handed with longer guests).
