Abstract

We synthesized dialkylterthiophene derivatives ω-substituted with cyclohexylethyl moiety, which exhibit smectic mesophases at room temperature, and investigated their charge carrier transport properties. In particular, trans-pentylcyclohexylethyl-propylterthiophene (3- TTP-C2CH-5) held SmB phase at room temperature. Furthermore, a 3: 1 mixture of 3-TTP- C2CH-5 and (2-methylbutyl)-dodecylterthiophene (5∗-TTP-12) showed the SmB phase ...
