| dc.description.abstract | The past few years have witnessed tremendous progress towards the design of new liquid crystalline (LC) materials comprised of rigid π-conjugated molecules, particularly disc shape molecules with appropriate substitution as an active component for the electronic device applications. Herein we report a new class of polycyclic aromatic hydrocarbons (PAHs) derived from pyrene core. These molecules are synthesized with 1, 6 dibromo pyrene and di-substituted arylethynylene via palladium-catalyzed cyclopentannulation followed by Scholl reaction. LC properties of these compounds were studied using a polarizing optical microscope, differential scanning calorimetry and X-ray diffractometry. Synthesized molecules show the hexagonal columnar mesophase over a wide range of temperatures. Pyrene derivatives have been extensively explored as novel dyes and widely used in various device applications. Therefore, these novel self-assembling supramolecular materials may find application in several optoelectronic devices. | en_US |
