Abstract
We report herein a series of tetrablock‐mimic azobenzene‐containing [60]fullerene dyads that form supramolecular liquid crystals (LCs) from phase‐segregated two‐dimensional (2D) crystals. The unique double‐, triple‐, and quadruple‐layer packing structure of fullerenes in the 2D crystals leads to different smectic supramolecular LC phases, and novel LC phase transitions were observed upon changes in the fullerene packing layer number in the 2D crystals. Interestingly, by combining the LC properties with 2D crystals, these materials show excellent electron mobility in the order of 10−3 cm2 V−1 s−1, despite their relatively low fullerene content. Our results provide a novel method to manipulate 2D crystal layer thickness, with promising applications in optoelectronic devices.
Hide your crystal ball: 2D crystals of a series of tetrablock‐mimic azobenzene‐containing fullerene dyads packed in double, triple, and quadruple layers formed supramolecular liquid crystals (LCs) with different smectic LC phases (see picture). Changes in packing caused novel LC phase transitions. The combination of LC properties with 2D crystals led to excellent electron mobility in these materials despite their relatively low fullerene content.
