This manuscript reports on an unusual self-assembly of small adenine-based molecules leading to complex, functional systems. Molecules feature an adenine nucleobase substituted at the N9 position with a triarylamine unit through a flexible spacer. Hydrogen bonding interactions prompt the formation of unprecedented adenine hexameric rosettes, which organize in dimers and then into helical columnar assemblies exhibiting hexagonal columnar liquid crystal phases, even with nonchiral molecules. Theoretical calculations including geometry optimization and prediction of vibrational modes have provided essential insight into the configuration of hydrogen bonds between adenine units to form stable hexads, and experimental and simulated X-ray diffraction (XRD) patterns are consistent with the unique helical self-assembly. Furthermore, molecular design including chirality in the flexible spacer and triarylamine electron-donor units steers these nanostructured materials toward functionalities related to the control of supramolecular chirality and semiconductivity. This is confirmed by thin film circular dichroism measurements for chirality and the space charge-limited current method for hole transport.
