, p. 695 - 696 (1985)
Highly aligned discotic liquid crystal fibres of hexa-alkoxytriphenylene (HET-n) and its ester derivative (HAT-n) can be drawn by a new strand technique; our synchrotron X-ray scattering study indicates the single crystal quality of these fibres.
Oxidative cyclotrimerization of unsaturated compounds with DDQ and triflic acid: An efficient synthetic route to triply-fused benzene rings
Cho, Hee Yeon,Scott, Lawrence T.
, p. 3458 - 3462 (2015)
Intermolecular oxidative cyclotrimerization reactions of alkenes and aromatic compounds with DDQ and trifluoromethanesulfonic acid are described. Scholl-type oxidation reactions involving alkenes have not previously been demonstrated. Moreover, the DDQ/acid system has never been used for intermolecular oxidative cyclization reactions. This convenient, metal-free reagent system (DDQ/TfOH) is advantageous with respect to metal-based Scholl-type oxidants because it eliminates the possibility of halogenation of aromatic compounds as a competing side reaction.
A new strategy towards the synthesis of a room-temperature discotic nematic liquid crystal employing triphenylene and pentaalkynylbenzene units
Gupta, Monika,Gupta, Santosh Prasad,Rasna,Adhikari, Debashis,Dhara, Surajit,Pal, Santanu Kumar
, p. 3014 - 3017 (2017/03/17)
A new approach is reported for the design of a room-temperature discotic nematic (ND) liquid crystal (LC) dimer consisting of a triphenylene and a pentaalkynylbenzene unit linked via flexible alkyl spacers. The formation of the ND phase is realized most likely through folding of the dimeric molecule that prevent stacking between the triphenylene units, as suggested by modelling in the mesophase derived from X-ray scattering results and high-level DFT calculations.
Triphenylene derivative and use thereof

, (2016/05/19)
A triphenylene derivative of general formula (I) or general formula (II) which can be used as a component of liquid crystal medium and the use thereof are provided in the present invention. This compound can be used to form a negative discotic liquid crystal composition having a suitable temperature range of liquid crystal phase and a lower clearing point, which can be used in TFT liquid crystal display as an optical compensation film (cell) material.
Self-organization of star-shaped columnar liquid crystals with a coaxial nanophase segregation revealed by a combined experimental and simulation approach
Beltrán, Eduardo,Garzoni, Matteo,Feringán, Beatriz,Vancheri, Alberto,Barberá, Joaquín,Serrano, José Luis,Pavan, Giovanni M.,Giménez, Raquel,Sierra, Teresa
supporting information, p. 1811 - 1814 (2015/02/05)
Fully consistent X-ray data and molecular dynamics simulations on new star-shaped liquid crystals yield two nanosegregated architectures with a coaxial stacking of two functional discotic units: tris(triazolyl)triazine and triphenylene. Analysis of lattice order along the principal axes reveals preferential staggered arrangement of the stacked molecules in the columnar assembly.
