Mesomorphic Properties of Oligosilanes with Phenyl End Groups

Oligosilanes with phenyl end groups, Ph(SiMe2)nPh where n = 10, 11, 12 and 13, were synthesized and their thermal and structural properties were studied. Dodecamer and tridecamer possessed mesophases showing the interdigitated structure in the range of 126–139 and 127–155 °C, respectively. In the me...

Zusammenfassung:Oligosilanes with phenyl end groups, Ph(SiMe2)nPh where n = 10, 11, 12 and 13, were synthesized and their thermal and structural properties were studied. Dodecamer and tridecamer possessed mesophases showing the interdigitated structure in the range of 126–139 and 127–155 °C, respectively. In the mesophase, the silicon chains adopted the all-trans conformation.
