Abstract

A triply fused copper porphyrin dimer, when site-specifically modified on its periphery with hydrophobic and hydrophilic wedges (1_C12/TEG), self-assembles into a columnar liquid crystalline (LC) mesophase over a wide-temperature range from -17 to 99 °C but gives rise to an amorphous solid when modified with only hydrophobic (1_C12/C12) or hydrophilic wedges (1_TEG/TEG). A LC film of 1_C12/TEG displays at 16 °C a top-class one-dimensional electron mobility (0.27 cm²/V·s), as evaluated from its maximum flash-photolysis time-resolved microwave conductivity.
