三稠合铜卟啉二聚体，当在其外围用疏水性和亲水性楔形物 (1C12/TEG) 进行位点特异性修饰时，会在 -17 至 99℃ 的宽温度范围内自组装成柱状液晶 (LC) 中间相，但当仅用疏水性 (1C12/C12) 或亲水性楔形物 (1TEG/TEG) 修饰时，会产生无定形固体。 1C12/TEG 的液晶薄膜在 16 摄氏度下显示出一流的一维电子迁移率 (0.27 cm2/V x s)，根据其最大闪光光解时间分辨微波电导率进行评估。
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.
