Synthesis, Characterization And Liquid Cryatal Properties Of μ-Oxo-bis[Meso-tetrakis (4-alkoxyphenyl) Porphyrin Aluminum(Ⅲ)]

Porphyrin compounds are provided with special configuration and nicer stability to heat and light, biggish visible light extinction coefficient, they are one of the best known self-assembly materials, and have special effect in the electric charge transfer process. Thus, they are wildly used in the field of electrochemistry, optical physics, analytical chemistry, radiology biomimetic chemistry.μ-Oxo-bis[meso-tetrakis(4-alkoxyphenyl)porphyrin Aluminum(Ⅲ)] complexes with different alkoxy chain length were synthesized,all were novel compounds.The structure of these compounds were identified through UV-vis, IR, MS and 1HNMR. The liquid-crystal properties of synthesized derivatives were studied through DSC and PM, most of them displayed liquid-crystal properties.
