Dendritic mols. with a fanlike or conelike conformation are common mol. building blocks to construct supramol. columnar or spherical phases. Although it is well-accepted that the preferred mol. conformation of dendritic mols. dictates their packing schemes, manipulation of this crucial parameter usually requires significant changes in mol. structures and tedious synthetic efforts. Herein, we report a simple yet highly efficient strategy to tune the mol. conformation of dendritic rodlike mols. by adjusting the length of alkyl side chains tethered to the rods. Strikingly, tiny chem. structure differences can largely change the “crowding” near the branching point to induce the “fanlike to conelike” conformational transitions and thus result in the formation of diverse supramol. structures, including the columnar phase, double gyroid phase, and the unconventional Frank-Kasper σ and A15 phases. Our study provides a practical platform for further investigation of unconventional structure formation and phase transitions in soft matter.
