Nanographenes with zig-zag peripheries are expected to have unique electronic properties, but their application in organic electronics has been curbed by their difficult synthesis. Here, the authors develop a facile route to zig-zag nanographenes bas

Herein, we report a new method for synthesis of extended perylenes and terrylenes. The technique is based on the cascade dehydrative π-extensions (DPEX) of aryl aldehydes, in which stepwise annulations activate previously "dormant" substituents. Two

A novel catalyst‐free approach to benzoannulated oxygen‐containing heterocycles from fluorinated oligophenylenes is reported. Unlike existing methods, the presented reaction does not require an oxygen‐containing precursor and relies on an exter

Caryl–F bond activation has become an important and quickly developing method for construction of carbon-based materials. We report that alumina-mediated C–F bond activation (AmCFA) enables construction of PAHs with zigzag periphery. This method

Polycyclic aromatic hydrocarbons with zigzag peripheries are high perspective candidates for organic electronics. However, large fused acenes are still poorly studied due to the tedious synthesis. Herein we report a non-substituted fused bistetracene

The synthesis of ten ortho-fused PAHs bearing boronic pinacol ester groups (BPin) is reported. The products are obtained via modification of Mallory photocyclization in 45–99% yields. Among them are examples of highly strained molecules such as [4]

An unprecedented [6]helicene's cavity closure indicating the possibility of introducing seven-membered rings via alumina-mediated C–F activation is shown. This finding, in combination with a directed quadruple annulation of fluorinated oligoarylene

Herein we report a transition-metal free activation of a particularly stable aromatic carbon–fluorine bond allowing intramolecular aryl–aryl coupling which is orthogonal to carbon–iodine functionality.
