“…Pentiptycene possesses a rigid H-shaped scaffold, which has found wide utility in supramolecular chemistry and materials chemistry, − such as fluorescent sensors, − molecular devices, ,, host–guest systems, , macrocycles, porous materials, − dynamic crystals, , and redox-active polymers. , The majority of these applications require substitutions on the central phenylene ring of pentiptycene. While the readily prepared pentiptycene quinone ( 1 ) serves as an ideal precursor for this purpose, , some of the derivatization of 1 toward the designated materials suffer from multistep synthesis and low overall yields.…”
