[25] We employed here a dichroic ratio (DRNPL) exhibiting azimuthal orientational order of azobenzene moieties. The value is defined here as DRNPL = (A1 ± A2)/A0, where A1 and A2 stand for absorbances at maximum absorption wavelength due to the p±p* transition of the E-isomer of the azobenzene, monitored by probing polarized light with the electric vectors parallel with and perpendicular to the incident plane of the oblique nonpolarized light, respectively. A0 indicates absorbance before photoirradiation. [26] K. Ichimura, M. Han, S. Morino, Chem. Lett. 1999, 85. [27] DLC (2) of 2,3,6,7,10,11-hexakis(4-octyloxybenzoyloxy)triphenylene exhibits ND and Dr phases (K 153 C Dr 168 C ND 244 C I). N. H. Tinh, H. Gasparoux, C. Destrade, Mol. Cryst. Liq. Cryst. 1981, 68, 101. [28] In the case of irradiation with linearly polarized light, the dichroic ratio (DRLPL) indicates a value of (A1 ± A2)/A0, where A1 and A2 are the maximum absorbances of the azobenzene monitored by probing light with the electric vector perpendicular to and parallel with that of the linearly polarized actinic light, respectively, in order to compare the value of DRNPL. [29] The optical phase difference indicates a difference between phase velocities of vertically and horizontally polarized light (sand p-polarized light) with respect to the oriented DLC film.
