Triphenylamine- and triazine- containing hydrogen bonded complexes: liquid crystalline supramolecular semiconductors

Despite the fact that triphenylamine derivatives have been widely explored as hole-transporting materials, studies on charge transport properties in the liquid crystal phase have been overlooked. Here, it is reported that triphenylamine liquid crystals can attain very high hole mobility values in a...
