| Research Abstract |
We have investigated the dependence of molecular structure of dendrimers peripherally with phenylnaphthalene group as a terminal mesogen on liquid crystalline nature and carrier mobility. All the dendrimers synthesized in this study exhibited highly ordered smectic liquid crystalline phases, and generated a high carrier mobility 10-2cm2/Vs. The liquid crystalline dendrimers having short terminal alkyl chains showed a dicotic columnar phase, and generated same carrier mobility as the smectic phase. Liquid crystalline dendrimer structure successfully gave thermodynamically stable liquid crystalline phases and high carrier mobility, and excellent molecular design for organic liquid-crystalline semiconductor.
