| Research Abstract |
The aim of this project was the molecular design and synthesis of low molecular weight gelators which were capable of gelling organic solvents and oils in the presence of a small amount of them. The clarification of gelation mechanism was another purpose of the project. We also studied the practical application of the developed gelators; for example, the preparation of porous polymers by in Situ precipitation, the preparation of inorganic hollow-fibers by using gelators as a template, and the preparation of gel-electrolytes by using gelators. We established the preparation method of porous polymer materials and inorganic hollow-fibers. With the non-leak solid electrolytes in mind, we made gel electrolytes by gelling ionic liquids with gelators. The dependence of ionic conductivities on the kind of gelators, temperatures, and concentrations was clarified.
For the suitable molecular design of gelators, we focused on L-lysine, L-glutamic acid, cyclic(dipeptide), (+)-2-arnino-l-pheny1-1,3-propanediol, and (-)-norephedrine as the cheap and available starting materials. Actually, new gelators were synthesized from these starting materials and their gelation ability towards organic solvents and oils was studied in detail. The gelation mechanism was investigated and clarified by DSC, SEM, and TEM.
