Novel nanoscale discotic liquid crystalline porphyrins 14 with partial alkyl chain perfluorination has been designed and synthesized in our group which exhibits exceptionally enhanced tendency to spontaneously self-assemble into homeotropically ordered nanostructures [107]. The defect-free homeotropically aligned fluorinated porphyrin thin films were fabricated and characterized. In the films thinner than 10 pm in glass cells, it shows strong tendency towards homeotropic... 

Due to the disc-like geometry of the porphyrin macrocycle, discotic mesophases have generally been the most common for porphyrin liquid-crystalline materials. The first porphyrin liquid crystals featuring rod-like calamitic mesophases were described by Bruce and coworkers using substituted 5,15-di(phenyl) zinc porphyrin complexes as the basic molecular building block.The first materials... 

The stacked porphyrin arrays assembled on DNA templates are reminiscent of the columnar liquid crystalline (LC) phases produced by discotic mesogens, including several porphyrin derivatives [67]. Different discotic compounds with complementary interactions have been shown to form mixed LC phases [68], a concept that has been extended to the DNA-templated porphyrin stacks [69]. The two porphyrins Hj-P4...
