Cruciforms: Assembling Single Crystal Micro- and Nanostructures from One to Three Dimensions and Their Applications in Organic Field-Effect Transistors

The self-assembly behaviors and charge transport properties of cruciforms with anthracene as one axis were studied. By changing one axis of these cruciforms, the assembly morphologies of single crystal micro/nanostructures transferred from one dimension to three dimensions. This morphology transformation was controlled by the intermolecular interactions of cruciforms, which was proved by single crystal X-ray diffraction results and presented a facile way to synthesize different dimensional micro/nanostructures through molecular design. Field-effect transistors based on individual single crystal micro/nanostructure exhibited high performance. These results suggested the potential applications of cruciform in organic electronics.
