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 and C 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.
期刊介绍：
The Journal of Porphyrins and Phthalocyanines (JPP) covers research in the chemistry, physics, biology and technology of porphyrins, phthalocyanines and related macrocycles. Research papers, review articles and short communications deal with the synthesis, spectroscopy, processing and applications of these compounds.
