Abstract
AbstractA series of oxygen‐ and sulfur‐bridged L‐shaped π‐electron cores (π‐cores) with Cs symmetry, dinaphtho [2, 1‐b:2′,3′‐d] furan (DNF−L) and dinaphtho [2, 1‐b:2′,3′‐d] thiophene (DNT−L), have been designed and investigated. DNF−L and DNT−L were successfully synthesized from commercially available 2‐methoxylnaphthalene in three and four steps, respectively. Notably, these compounds exhibited extremely high solubility in common organic solvents even without substituents and excellent thermal and chemical stability. X‐ray single‐crystal structural analyses of DNF−L and DNT−L reveal that both molecules form herringbone‐type packing structures suitable for two‐dimensional charge transport, but the packing of DNT−L has a large displacement in the direction of the longitudinal axis. Moreover, DNF−L shows a charge carrier mobility of up to 1.5 cm2/Vs in single‐crystal transistors, indicating that these L‐shaped molecules have excellent potential as organic semiconducting backbones with high solubility and high thermal and chemical stabilities.
