Organic Two‐Dimensional Assembly with Rectification Property Mediated by Cucurbit[8]uril

Abstract We report a highly regular organic two‐dimensional assembly made of cucurbit[8]uril and aromatic units that shows peculiar optoelectronic properties. We found that this individual self‐assembled microplate displayed a good conductivity under forward bias but nearly no current was detected under reverse bias along the stacking direction. This unique phenomenon is due to the coordination assembly of cucurbit[8]uril with aromatic units and aromatic stacking between layers. Moreover, the fluorescent properties are maintained in the solid state. Our result might show advantages in fabricating optoelectronic devices and help others to design organic two‐dimensional materials with specific functions.
