Abstract Series of novel triazole polycatenar bent-shaped molecules comprising a carbonyl central core with two 1,2,3-triazole dendritic wings have been firstly synthesized via the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. The effect of variation of the number and length of the terminal alkyl chains as well as the dendritic generation, linkage group on their properties have been investigated by polarizing optical microscopy (POM), differential scanning calorimetry (DSC), X-ray diffraction (XRD), scanning electron microscope (SEM) and photoluminescence measurements. It is found that these compounds can self-assemble into hexagonal columnar and micellar cubic phases in their pure states, as well as organogels in organic solvents. In addition, fluorescence spectroscopic studies demonstrate that they can act as chemosensor of metal ions. The ester compounds exhibit dual selectivity for Fe3+ and Hg2+, while the ether compounds show exclusive selectivity for Fe3+ ion.
