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.
合成了具有苯基端基的低聚硅烷 Ph(SiMe2)nPh,其中 n = 10、11、12 和 13,并研究了它们的热和结构特性。Dodecamer 和 tridecamer 具有中间相,分别在 126-139 和 127-155 °C 的范围内显示交叉结构。在中间相,硅链采用全反式构象。
