The conceptual connections between [4n] Hückel antiaromaticity, disjoint orbitals,
correlation energy, pro‐aromaticity and diradical character for a variety of extended π …

Non‐alternant non‐benzenoid π‐conjugated polycyclic hydrocarbons (PHs) are expected to
exhibit very different electronic properties from the all‐benzenoid PHs. Herein, we report the …

The chemistry of nonalternant hydrocarbons has recently experienced a considerable
resurgence. As the relationship between naphthalene and azulene shows, an important …

Develo** open-shell singlet (OS) diradicals with high luminescent properties and
exceptional single-molecule magnetoluminescence (ML) performance is extremely …

Whether tetra‐tert‐butyl‐s‐indacene is a symmetric D2h structure or a bond‐alternating C2h
structure remains a standing puzzle. Close agreement between experimental and computed …

It is very challenging to obtain stable room‐temperature luminescent open‐shell singlet
diradicals. Herein we report the first stable Müller's hydrocarbon TTM‐PhTTM with …

Molecules where the first excited singlet state is lower in energy than the first excited triplet
state have the potential to revolutionize OLEDs. This inverted singlet–triplet gap violates …

Polycyclic hydrocarbons consisting of two or more directly fused antiaromatic subunits are
rare due to their high reactivity. However, it is important to understand how the interactions …

The π-magnetism of finite-sized nanoribbons occurring on the topological molecular
interfaces remains largely unexplored due to limited experimental examples. Herein, we …

We herein present the synthetic approach to a new antiaromatic double aza [7] helicene C
that features NN‐embedded polycyclic aromatic hydrocarbons (PAHs). This heteroatom …
