A series of poly(di-n-alkyl)silane copolymers derived from Poly(di-n-hexyl)silane, PDHS, was prepared. Mesomorphic phase transitions of these copolymers depend on fraction as well as on the size of the comonomers. DSC and temperature dependent UV-spectroscopy were employed to study the effect of constitutional disorder on the length of all-trans σ-conjugated Si---Si catenated chromophores.
