We have synthesized two novel phthalocyanines, (m-SF5PhO)(8)PcCu (7b) and (p-SF5PhO)(8)PcCu (7c), in order to investigate their flying-seed-like mesomorphism. Their phase transition behavior and the mesophase structure have been established by using a polarizing optical microscope, a differential scanning calorimeter, and a temperature-dependent small angle X-ray diffractometer. Very interestingly, the derivative (m-SF5PhO)(8)PcCu (7b) substituted a SF 5 group at m-position showed a Col(10)(P2(1)/a) (= p2gg) mesophase from rt to 315.0 degrees C, whereas the derivative (p-SF5PhO)(8)PcCu (7c) substituted a SF 5 group at p-position showed a crystalline (K) phase from rt to the decomposition temperature at ca. 336 degrees C without showing mesomorphism. Thus, the novel phthalocyanine derivative (m-SF5PhO)(8)PcCu (7b) substituted a strong electron withdrawing SF 5 group at m-position shows only one columnar mesophase in a very wide temperature region from rt to 315.0 degrees C. Furthermore, the Q-band wavelengths (672.2 and 672.1 nm) of the present (m-SF5PhO)(8)PcCu (7b) and (p-SF5PhO)(8)PcCu (7c) are shorter than that (680.3 nm) of the previous [(m-C-1) PhO](8)PcCu (5c) derivative. It can be attributed to strong electron withdrawing nature of the SF5 group on the phenoxy group. |
