A triply fused copper porphyrin dimer, when site-specifically modified on its periphery with hydrophobic and hydrophilic wedges (1C12/TEG), self-assembles into a columnar liquid crystalline (LC) mesophase over a wide-temperature range from -17 to 99 degrees C but gives rise to an amorphous solid when modified with only hydrophobic (1C12/C12) or hydrophilic wedges (1TEG/TEG). A LC film of 1C12/TEG displays at 16 degrees C a top-class one-dimensional electron mobility (0.27 cm2/V x s), as evaluated from its maximum flash-photolysis time-resolved microwave conductivity.
一种三重稠合的铜卟啉二聚体，当其在周边通过疏水和亲水楔形物（1C12/TEG）进行位点特异性修饰时，在从 -17 至 99 摄氏度的宽温度范围内自组装成柱状液晶（LC）中间相，但仅用疏水楔形物（1C12/C12）或亲水楔形物（1TEG/TEG）修饰时会形成无定形固体。1C12/TEG 的液晶膜在 16 摄氏度时表现出一流的一维电子迁移率（0.27 cm²/V·s），这是根据其最大闪光光解时间分辨微波电导率评估得出的。
