Zethrenes are model diradicaloids with potential applications in spintronics and optoelectronics. Despite a rich chemistry in solution, on-surface synthesis of zethrenes has never been demonstrated. We report the on-surface synthesis of super-heptaze

The title compound, C50H44, 1, was synthesized as a derivative of heptazethrene bearing two methyl and two tert-butylphenyl substituents, respectively, at the 1,9- and 7,15-positions. The asymmetric unit consists of one half of the molecule, which li

We report the synthesis and characterization of sulfur-doped dibenzoheptazethrene (DBHZ-2S) and dibenzooctazethrene (DBOZ-2S) dications. Their neutral precursors 9a/9b were synthesized by acid-medi...

We report the synthesis and electronic properties of nitrogen-doped heptazethrene (HZ) and octazethrene (OZ) diradicaloids, including the parent HZ-1N and OZ-1N, and the N-aryl-substituted dications, HZ-2N and OZ-2N. The unprotected HZ-1N and OZ-1N w

Fusing two phenalenyl units such that a Kekule structure is obtained leads to ‘biradicaloid’ systems, which typically display low singlet–triplet (S–T) energy gaps. The value of the S–T gap in biradicaloids can be lowered by extending the

A soluble and stable heptazethrene derivative was synthesized and characterized for the first time. This molecule exhibits a singlet biradical character in the ground state, which is the first case among zethrene homologue series. Exceptional stabili
