Conspectus Highly conjugated hydrocarbons have attracted interest for use as active
materials in electronic devices such as organic field effect transistors (OFET) and organic …

The literature has seen a large increase in the number of new carbon‐based organic
diradicals/diradicaloids in recent years. While a plethora of new and exciting structures have …

Many qualitative structure–property correlations between diradical character and emerging
molecular properties are known. For example, the increase of diradical character further …

Understanding and controlling the electronic structure of molecules is crucial when
designing and optimizing new organic semiconductor materials. We report the …

Since the first isolation of 1, 3, 5, 7-tetra-tert-butyl-s-indacene in 1986, core-expanded s-and
as-indacenes have attracted intensive interest. However, there is no reported synthesis of …

Though s-indacene is an intriguing antiaromatic hydrocarbon of 12 π-electrons, it has been
underrepresented due to the lack of efficient and versatile methods to prepare stable …

The rapid emergence of organic (opto) electronics as a promising alternative to conventional
(opto) electronics has been achieved through the design and development of novel π …

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 …

Of the five possible indenofluorene regioisomers, examples of a fully conjugated indeno [1,
2‐a] fluorene scaffold have so far remained elusive. This work reports the preparation and …

Organic field-effect transistors (OFETs) have received significant interest due to potential
applications from low-cost active circuit to wearable health care devices. Organic …
