Building PAH molecules from APEX reactions. Credit: Issey Takahashi Nanographenes are organic semiconductor materials used in smartphones, OLED displays, and solar cells. At the molecular level, they are composed of polycyclic aromatic hydrocarbons (PAHs), which are a network of connected benzene rings (hexagon-shaped carbon molecules). Chemists can modify the electronic properties of PAHs by adding more benzene rings to them, changing their size and shape. As such, there is high demand for methods that can selectively extend specific sites of PAH molecules to allow greater versatility in technological applications. Depending on their size, the peripheral regions of the PAH skeletons can be categorized as K, M, L, bay, and fissure regions. Previously, researchers from Nagoya University developed the Annulative π-Extension (APEX) reaction that transforms small PAHs into larger PAHs and nanographenes by extending these regions.…
