Room Temperature Discotic Liquid Crystalline Thin Films of Hexa-peri-hexabenzocoronene : Synthesis and Optoelectronic Properties

The compound hexa-(3,7,11,15-tetramethylhexadecanyl)hexa-peri-hexabenzocoronene (HBCC4/16), soluble in most organic solvents such as chloroform and THF, was synthesized. This compound shows a stable discotic hexagonal columnar mesophase between -36 and 231 °C. Symmetrical sandwich cells of ITO/HBC-C4/16/ITO (∼1 μm thick) were prepared by capillary filling… CONTINUE READING
