Synthesis of conjugated-bridged triphenylenes and application in OLEDs
Freudenmann,Behnisch,Hanack
, p. 1618 - 1624 (2001)
Novel conjugated-bridged triphenylene derivatives with electroluminescent properties were synthesized. A six step synthesis yields the cyanomethyltriphenylene derivatives (7a-7d). These were condensed by applying a Knoevenagel reaction with the alkoxy sub
Synthesis of unsymmetrical dibenzoquinoxaline discotic mesogens
Foster, E. Johan,Babuin, Jarret,Nguyen, Natalie,Williams, Vance E.
, p. 2052 - 2053 (2007/10/03)
Unsymmetrical dibenzophenazine discotic mesogens were prepared via the corresponding tetraalkoxybenzfl derivatives. These dibenzophenazines exhibit Colho phases over extremely broad temperature ranges.
Orientational ordering and dynamics in the columnar phase of a discotic liquid crystal studied by deuteron NMR spectroscopy
Shen,Dong,Boden,Bushby,Martin,Wood
, p. 4324 - 4332 (2007/10/03)
The quadropolar splittings and the spin-lattice relaxation data measured in the columnar phase of two differently deuterated HAT6 molecules are interpreted. Modeling the splittings using the AP method allows to obtain the orienting potential needed to describe the reorientational dynamics of molecular disks. It is emphasized that the tumbling motion of a disk can be slightly faster than its spinning motion.
