Abstract
Five simple benzenecarboxamide (BC) derivatives bearing multiple −CONHC14H29 chains—N,N′-bis(tetradecyl)-1,4-benzenedicarboxamide (2BC), N,N′,N″-tri(tetradecyl)-1,3,5-benzenetricarboxamide (3BC), N,N′,N″,N″-tetra(tetradecyl)-1,2,4,5-benzenetetracarboxamide (4BC), N,N′,N″,N‴,N′′′′-penta(tetradecyl)benzenepentacarboxamide (5BC), and N,N′,N″,N‴,N′′′′,N′′′′′-hexa(tetradecyl)benzenehexacarboxamide (6BC)—were examined in terms of their molecular assemblies in solution, organogels, liquid crystals, and solids as well as their phase transition behavior and dielectric responses. The molecular assemblies of compounds 3BC–6BC were dominated by the intermolecular N–H∼O= hydrogen-bonding interactions along the π-stacking directions and formed one-dimensional π-stacking nanofibers. The excellent organogelation characteristics of compound 3BC were observed in common organic solvents such as ethanol, acetonitrile, acetone, and N,N-dimethylformamide, whereas compounds 4BC and 6BC formed organogels in hexane and/or toluene...
