Self-assembling dendronized ionic-liquids containing triethyl and tripropyl ammonium, pyridinium and 3-methylimidazolium chloride, tetrafluoroborate and hexafluorophosphate at their apex were synthesized. These minidendrons self-assemble into supramolecular cylindrical or spherical dendrimers at elevated to room temperature ranges, which in turn self-organize into 2-D hexagonal or 3-D cubic liquid crystalline lattices. Their structural and retrostructural analysis has demonstrated the first examples of ionic liquid mediated self-assembly of columnar and spherical supramolecular dendrimers containing columnar and spherical nanoscale ionic liquid reactors segregated in their core.
