Abstract

Organogels have become one of the hot areas in soft matter and new energy field due to their scientific values and many potential applications. Herein we reported the gelation behaviours of binary trigonal acids and bipyridine derivatives mixtures in various organic solvents. Their gelation behaviours in 20 solvents were tested as new organic gelators. It was shown that the molecular shapes and substituent groups in these compounds played a crucial role in the gelation behaviour of the mixed compounds. While the trigonal acid with aromatic core can gel in acetone and ethanol, another trigonal acid with hydrophobic core can only gel in aniline. Morphological observations reveal that the molecular structures and the identity of the solvents are the main factors affecting the structures of the aggregates in the gels. Experimentally, different microstructures of the gels were observed. As example, the aggregates of trigonal compound in acetone, ethanol, or aniline adopt structures of belt-like aggregates or thin nanofibres, respectively.
