We have synthesized a novel type of donor-acceptor liquid crystalline material, phthalocyanine-fullerene (Pc-C-60) dyad, [m,p,m'-(C14O)(3)PhO](6)PcCu-C-60 (7), and the Pc precursors, [m,p,m'-(C14O)(3)PhO](6)PcCu-OFBA (6) and [m,p,m'-(C14O)(3)PhO](6)PcCu-OH (5), and established their mesomorphism by using a polarizing optical microscope, a differential scanning calorimeter and a small angle X-ray diffractometer. Very interestingly, their corresponding previous parent Pc derivative, [m,p,m'-(C14O)(3)PhO](8)PcCu (4), shows a very wide temperature region ca. 90 degrees C of a bicontinuous Cub(Pn3m) mesophase, whereas the present children Pc precursors (5 and 6) and Pc-C-60 dyad 7 show not the Cub mesophase but a Col(ho) mesophase. It is also noteworthy that the staking distance in the Col(ho) mesophase of the Pc-C-60 dyad 7 was a very big value of ca. 9.1 angstrom, which is the biggest in discotic liquid crystals to our best knowledge. It may be originated from the biggest excluded volume caused by thermal fluctuation of peripheral long alkoxy chains at m, m'-positions. The excluded volume caused by thermal fluctuation of the peripheral long chains is so big that the molecular shape of the Pc derivative 4 and the Pc-C-60 dyad 7 very resembles a flat pumpkin. |
