Molecular Design, Construction And Structural Characteration Of Nanorod Micelle Built By Liquid Crystal Unit

In this paper,liquid crystal unit consisted by rigid and flexible structure was prepared based on the methods of chemical synthesis and self-assembly with transition metal ions and organical ligands in the view of molecular design.Nanorod-micelle was formed by hydrophobic effect and - stack in the relevant solvent.In the first place,the surfactantal liquid crystal unit composed by azo-benzene and dodecyl was synthesized.The steady nanorod-micelle was formed by upright-neaten effect of sulfonated group and - stack in the cyclohexane.In the second place,me disc-like liquid crystal unit was prepared with 4-carboxylpyridine dodecylester as liquid cystal ligand coordinated with transition metal ions(Pd(II) , Cu(II), Ni(II)). The steady nanorod micelle was formed by hydrophobic effect, weak coordination effect to which metal ions reacted eletron and - stack in the cyclohexane.Finally,the Schiff base was choosed as ligand to study the adjustive function to the morphology of nanorod micelle above.The structure of the synthesized complexes is characterized by element analysis ,FTIR,UV, fluorescence spectra and TG-DTA. The self-assembled nanorod morphologywith the size of 10nm-60nm is observed by TEM.The study would be expected to take on some referenced value to the study of preparation of nano-materials and new application of nano-materials for the future.
