Abstract
New stereoregular cis-penta[(phenyl)(trimethylsiloxy)]cyclopentasiloxane cis-[PhSi(O)(OSiMe3)]5 was synthesized. According to the data from DSC, X-ray diffraction, and polarization microscopy, the noncrystallizable cyclopentasiloxane exists in the mesomorphic state throughout the temperature range below the temperature of destruction and is transformed into mesomorphic glass below the glass transition temperature. This compound possesses the polymesomorphic properties and forms two mesomorphic modifications. The type of mesomorphic ordering for these modifications was determined.
