Description
Summary:We report on the design and synthesis of a new discotic liquid crystalline (LC) semiconducting material based on a triphenylene core. The molecule is readily soluble in common organic solvents to exhibit self-organizing long fiber structures with supramolecularly ordered columnar stacks that lie parallel to the substrate. Compared to all the previously reported triphenylene derivatives, this molecule has a relatively lower band gap energy (Eg = 2.53 eV), which makes it suitable for electronic and optoelectronic applications.
