synthesized compounds protected with various linear saturated fatty acids (C-GL series) in only one step for developing novel organogelators. In all cases, the compounds were obtained in which the sixmembered ring structure was changed to a five-membered ring structure (1,4-GL). We believe this is because the five-membered ring is thermodynamically more stable when the fatty acid is introduced into the 6-position hydroxy group of 1,5-GL. The C-GL series synthesized here inferior gelation ability compared to C16AG, an existing gelator with six-membered ring structure. The first reason for this is thought to be weakening of the intermolecular packing force due to the increased degrees of freedom of the carbons at 5-and 6-positions of the five-membered ring. Furthermore, this may be reflected in the xerogel structure, as revealed by FE-SEM observations. Compounds with molecular chains longer than 16 carbons form a porous structure with irregular plate-like crystals rather than the fiber structure typical of LMG. However, XRD measurements of C12GL to C18GL showed a lamellar structure with regularly arranged molecules. The existing LMG, C16AG, has a lamellar structure, forming a fiber structure with a diameter of 100-200 nm. When the lamellar structure extends in one direction, fibers are formed, but when it extends in multiple directions, plate-like crystals are formed.
