Triphenylenes are a class of polycyclic aromatic hydrocarbon that have been attracting increasing attention owing to their widespread applications in areas such as liquid crystals, organic electronics and photovoltaics.
We present discotic liquid crystals consisting of fluorinated triphenylene with unusually short tails, including mere methoxy or ethoxy tails. Understanding these short-tailed liquid crystals may lead to new applications for discotic liquid crystals.
An uncommon approach to the synthesis of ambipolar semiconductors based on di- and tri-nuclear gold isocyano–triphenylene complexes of the formula [(AuX)n(CN–C6H4–O–(CH2)6)n–TriPh] (n = 2, 3; X = Cl, C
C–Ph) is described.
This work reports new soft photothermal materials based on mesomorphic nickel bis(dithiolene) complexes bearing pentakis(dodecyloxy)triphenylene units, in which the triphenylene core and the metal complex are linked through alkyl connectors.
Novel fluorine discotic liquid crystals, synthesized by arene–fluorine nucleophilic substitution reaction, form stable columnar hexagonal mesophases due to the establishment of long-range non-covalent perfluoroarene-arene intermolecular interactions.
