摘要

Two series of 5-iodo-1,2,3-triazole derivatives containing azobenzene group(s) were synthesized and their gelling properties were tested. Those containing two azobenzene groups ( series) have better gelation performance than those containing one azobenzene group ( series). The microstructure of organogels and the driving force of gelation were investigated by scanning electron microscopy and H NMR, respectively. It was found that π-π stacking, van der Waals interaction, and dipole-dipole interaction were the main forces of gelation. All the tested organogels are photoresponsive and those from series are smarter than that from series. Henry - diagrams of compounds , , and were constructed on the basis of their gelation performance and the Hansen solubility parameters of related solvents. The constructed Henry - diagrams can be used to estimate the behavior of three compounds in any untested solvent.
