Outline of Final Research Achievements

We have accomplished the synthesis of metal complexes of [7]-helicene bearing a cyclopentadiene moiety in the middle ring starting from optically active biphenanthrol. The helicene cyclopentadienyl anion was complexed with Ru(II) ion to form a complex consists of one helicene per Ru(II) and one consists of two helicenes per Ru(II). Their chiroptical natures were elucidated both in a solution and in a solid state. In addition, a complex consists of one helicene and two Ru(II) centers was synthesized. This complex exhibited unique phosphorescence emission, which could be attributed to the electron transfer between the two metal centers.
