A linear-shaped bi-1,3,4-oxadiazole derivative, oxalyl acid N′,N′-di(4-(2-ethylhexyloxy)benzoyl)-hydrazide (FH-Z8) was designed and synthesized. Quadruple hydrogen bonds between bi-dihydrazide units and π-π interactions cooperatively participated in forming supramolecules in chloroform at higher concentrations of FH-Z8. The association constants (K) in chloroform were 2.2×103 and 1.8×103 M-1 based on NH1 and NH2 in FH-Z8, respectively. FH-Z8 could gel dichloroethane efficiently with the critical gelation concentration (CGC) of 0.14 wt %, while spontaneously crystallized from the gel during storage.
