TL;DR: Graphene, a two-dimensional layer of sp(2)-hybridized carbon atoms, can be viewed as a sheet of benzene rings fused together, leading to an entire family of phenalenyl derivatives--'open-shell graphene fragments'--that are of substantial interest from the standpoint of fundamental science as well as in view of their potential applications in materials chemistry, in particular quantum electronic devices.

TL;DR: This work demonstrates organic tailored batteries with high capacity by using organic molecules with degenerate molecular orbitals (MOs) as electrode-active materials, exceeding those delivered by Li-ion batteries.

TL;DR: A teranthene derivative has been successfully isolated in a crystalline form for the first time and geometric considerations and physical property investigations indicate that the molecule possesses prominent biradical character in the ground state.
