    • The dipole moment along the long axis of LC1 was estimated 5.3, whereas that of the short axis was 1.6 using MOPAC (PM3).

    • Both materials were purchased from Merck Japan Ltd. TL213 has a positive dielectric anisotropy (δ∈ ≅ +5.7), and the refractive index was no = 1.527, δ n = 0.239. The liquid crystal material (ME-1), which has the negative value of dielectric anisotropy, was specifically produced; δ∈ ≅ -4.9, no = 1.489, δn = 0.124. The mixture consists of 46 wt % TL213 and 54 wt % ME-1 so as to lead to "zero" dielectric anisotropy. The physical properties of the mixture were δ∈ ≅ 0, no = 1.506, δn = 0.177.

    • note
    • 1.540 of the refractive index for LC1 was used for the SPR measurement. The calculation of MOPAC (PM3) estimated that the length of LC1 was 31 Å. Considering the tilt angle (30°) of the alkyl chain to stabilize the lateral packing of the LC1 SAM on gold, the estimated thickness from this assumption was approximately 27 Å. The result of the SPR indicated the thickness of the LC1 SAM was approximately 25 Å. The difference may be caused by either the influence of the anisotropic factor of the refractive index or by the minor contribution of the ether bond to bend the terphenyl moiety.
