Cover Feature: Open‐Shell Characters, Aromaticities and Third‐Order Nonlinear Optical Properties of Carbon Nanobelts Composed of Five‐ and Six‐Membered Rings (Asian J. Org. Chem. 11/2018)

The cover picture shows open‐shell and aromatic characters of a theoretically designed carbon nanobelt (CNB) composed of five‐ and six‐membered rings. Quantum chemical calculations and magnetically‐induced current density analysis have revealed that in the presence of repeating indeno[1,2‐b]fluorene (IF) substructures, the IF‐CNB bearing (4n+2)π electrons is expected to exhibit both intermediate open‐shell character and strong aromatic nature. Such features are suitable for applications to third‐order nonlinear optical systems.
