摘要
Series of novel bent-shaped polycatenar molecules consisting of bisphenylsulfone as the central core and two 1,2,3-triazole dendron as wings were synthesized by copper(I)-catalyzed azide-alkyne cydoaddition (CuAAC) reaction. These compounds can self-assemble into liquid crystalline phases in their pure states and organogels in organic solvent. Hexagonal columnar and Pm & Unknown;n cubic phases are displayed by these compounds. Interestingly, the gel shows three dimensional networks of nanofibers. However, with the increasing of aging time, the nanofiber transforms into microspheric morphology, which is constructed by entangled fibers. Moreover, the gel system can be established to remove I-2, Fe3+ and rhodamine B (RhB) from wastewater.
