The modification of the peptide is performed easily by the
replacement of [Ru(tpy)2]2+ with various rigid groups. This result
could trigger a wide variety of other parallel studies, such as various
expanded poly(L-leucine)s or expanded poly(R-amino acid)s, which
will lead to new functionalized molecules.

elongating peptide chain (Figure 2b). The CD spectra do not show
typical exciton splitting, which is attributed to electric dipole
moments in chromophores and is usually observed in chiral
octahedral complexes.17,18 Thus, the intense positive Cotton effects
predominantly arise from electron movement along a right-handed
(P) helix, as found in helicates.18-20 The enhancement of the CD
signal indicates the formation of a well-defined helical structure.

leucine residue was determined by the simulated annealing (SA)
method21,22 using the NMR constraints of 4. The obtained lowest-
energy structure and the reported crystal structure23 of [Ru(tpy)2]2+
were applied to the molecular dynamics calculation24 of 4. The final
structure is shown in Figure 3. The molecule exhibits a right-handed
(P) 41 helix with two dihedral angles (φ ) -146°, ψ ) 30°), which
are appropriate for n ) 4 (n is the number of residues per turn).25,26
The pitch is calculated to be 57 Å, and the dimensions of the helix
are 18 × 28 × 70 Å3.

In summary, we have defined and constructed “expanded oligo-
(L-leucine)”. The helical structure is determined by two torsion
angles, φ and ψ. Electrostatic repulsion between dicationic ruthe-
nium moieties probably contributes to the stabilization of the
extended helix with a long pitch. When a more polar solvent, such
as dimethyl sulfoxide (DMSO), was used instead of acetonitrile,
the intensity of CD decreased (Figure S7 of the Supporting
Information). However, the most important factor is restriction of
the torsion angles (φ, ψ). Even if a neutral rigid group is used (e.g.,
t-BuCONHC6H4CO-(Leu-NHC6H4CO)n-NH-t-Bu), the normalized
CD intensity increased with the elongation of peptide chain (Figure
S8 of the Supporting Information). These results suggest that the
electrostatic repulsion is not essential but affects the stabilization;
additionally, the thermal motion breaking the whole helical structure
is limited in the longer chain.
