Abstract
A series of dialkylterthiophenes, CH3(CH2)(n)-TTh-(CH2)(n),CH3 (TTh=te rthiophene, n=3,5,7,9,11) were synthesized and characterized. All the dialkyl-substituted terthiophenes display smectic mesophase except dib utylterthiophene exhibiting only a crystal melting. The thermal stabil ity of the mesophase of dialkylterthiophene increases with increasing the length of alkyl chains. The complexation of the dialkyl terthiophe nes with CpRu suppresses liquid crystallity and all the complexes bec omes amorphous.
