Flat-on ambipolar triphenylamine/C₆₀ nano-stacks formed from the self-organization of a pyramid-sphere-shaped amphiphile.

ABSTRACT: A giant amphiphile, which is constructed with an amorphous nano-pyramid (triphenylamine, TPA) and a crystalline nano-sphere (C₆₀), was synthesized. Structural characterization indicates that this pyramid-sphere-shaped amphiphile (TPA-C₆₀ ) forms a solvent-induced ordered phase, in which the two constituent units self-assemble into alternating stacks of two-dimensional (2D) TPA and C₆₀ nano-sheets. Due to the complexity of the molecular structure and the amorphous nature of the nano-pyramid, phase formation was driven by intermolecular C₆₀-C₆₀ interactions and the ordered phase could not be reformed from the TPA-C₆₀ melt. Oriented crystal arrays of TPA-C₆₀ , which contain flat-on TPA/C_60</
