Heat capacities of dibenzofuran and fluorene were measured with an adiabatic calorimeter in the temperature ranges 245Q(T/K)Q375 and 200Q(T/K)Q419, respectively. Glass transitions were discovered at Tg=316 K for both the compounds in the stable crystalline state due to freezing-in of the reorientati

## Abstract The synthesis of side‐chain liquid crystalline copolysiloxanes containing ω‐[4‐[4‐[(__S__)‐2‐methylbutoxy]phenoxycarbonyl]‐2‐chlorophenoxy]alkyl side groups is presented. Differential scanning calorimetry, optical polarizing microscopy and X‐ray diffractometry reveal smectic mesomorphis
