Abstract

Two novel porphyrin liquid crystals were designed and synthesized. Their structures were characterized by NMR, FT-IR, UV-visible, and mass spectroscopies. The liquid crystalline properties were investigated by DSC, POM and XRD analyses. The C[Formula: see text] and C[Formula: see text] alkyl chains porphyrin iron(III) complex (1-2) displayed three liquid crystalline transitions in a wide temperature range. Both long alkyl chain porphyrin iron(III) complexes were exhibited a columnar mesophase type.
