AbstractA new polyorganosiloxane (POS) was synthesized successfully according to two plus two (2 + 2) mode by hydrosilylation reaction of reactive cis-isotactic ladder-like polyallylsilsesquioxane (Allyl-T) with coupling agent 1,1,3,3-tetratizetliyldisiloxane (H-MM) using di-cyclopentadienyl-dichloroplatinium (Cp2PtCl2) as catalyst. Moreover, a novel supramolecular POS clathrate (POS/C) was formed by in situ encapsulating rod-like liquid crystal molecule within the pore of POS. The Allyl-T was prepared by stepwise coupling polymerization. A variety of characterization methods including solubility test, FT-IR, H-1 - NMR, differential scanning calorimetry (DSC) gel permeation chromatography (GPC), vapor pressure osmometry (VPO), X-ray diffraction (XRD), atomic force microscopy (AFM), polarized optical microscopy (POM) and molecular simulation not only indicates nano-scale tubular structures exist in the POS though some defective structures still exist, but also proves that novel soluble supramolecular clathrate has been formed.
