受賞対象となった研究の内容
Artificial molecular machines are molecules capable to execute mechanical-like movements as an outcome of an appropriate external stimuli. There are now many examples like motors, shuttles, tweezers, nanocars and gears. Various kinds of molecular gears have been proposed, among them, double-decker complexes, in which lanthanoid ion is sandwiched between two porphyrinoid ligands such as porphyrin or phthalocyanine, attractive structural motifs for molecular gears since the ligands can rotate around the metal ion.
In the awarded presentation, she reported the construction of double-decker complexes of Cerium(IV) as new prototypes of molecular gears. Phthalocyanines substituted at the α-position with π-planar bulky substituents were used to synthesize two homoleptic and one heteroleptic double-decker complexes. It is expected that the upper and lower ligands tightly engage and work as gear due to these bulky and rigid substituents. To study molecular gearing on surface with STM, our final target is constituted of a thioether-functionalized porphyrin as anchoring ligand and a carbazole-functionalized naphthalocyanine as cogwheel. Thanks to the helical chirality of this double-decker complex, we hope to build a train of gears with consecutive molecules of opposite chirality.
