Synthesis Of The Amphiphilic Compounds And Their Applications In The Preparation Of Nanomaterials

Because of the excellent performance, nanomaterials have been extensively studiedin the optoelectronic field. The materials used in optoelectronic devices focused on hybridsilica, nano-fullerenes and PBI derivatives nowadays, which are expected to form orderednano-structure. Therefore, finding a convenient and efficient way to control morphology isstill a huge challenge at present.On the other hand, amphiphilic compounds, especially low weight molecules have awide usage since they have many kinds and can be controllable synthesis. To furtherresearch the application of amphiphilic molecules in fabricating controllablenanomaterials, we synthesized hybrid silica, nano-fullerenes and nano-PBIs.1) We synthesized a hybrid silica precursor with L-alanine segment; NMR and SEMcharacterize the structure of the silsesquioxane monomer. Moreover, we can find out inSEM that the silsesquioxane can form mesh structure in THF in the existence of NEt3.2) We designed and synthesized two easy-access gelators named G1and G2, both ofwhich can form stable thermal reversible physical gel in toluene. More importantly, C60can form nano-rods co-assemble with G1or G2. Based on the results of scanningmicroscopy, high-resolution transmission electron microscopy, and energy-dispersiveX-ray spectroscopy, a tentative explanation has been proposed.3) We designed and synthesized a amphiphilic molecular named perylene-A,containing both a hydrophilic head group and a hydrophobic head group. In our studies,we found that perylene-A can form nano-spherical structure in ether/Methylene system,nano-wires while in methanol/chloroform system. Because of the chelation betweenperylene-A and sodium ion, when assembled in solution, perylene-A was also affected.SEM, TEM, NMR and UV-Vis confirmed these results.
