Discotic block codendrimers , consisting of two different nonmesogenic aliphatic polyether dendrons and a discotic linker, exhibited induced hexagonal columnar and bicontinuous cubic (unprecedented in dendrimers) liquid‐crystalline (LC) phases by the addition of lithium salt (see figure). The interior and exterior of these morphologies can be altered by changing the majority dendritic block.
