Vloeibaar-kristalinrichting

A liquid crystal device wherein the liquid crystal material exhibits a smectic phase and cromprises at least one siloxane compound having the general formula in which R=alkyl, alkenyl or aryl, Q represents a monovalent group, for example alkyl -(CH2)nOM', a chiral organic group, a dye group, a...

More Information
Summary:A liquid crystal device wherein the liquid crystal material exhibits a smectic phase and cromprises at least one siloxane compound having the general formula in which R=alkyl, alkenyl or aryl, Q represents a monovalent group, for example alkyl -(CH2)nOM', a chiral organic group, a dye group, a non-linear optic group or the group -(CH2)nL in which L represents a siloxane group, M and M' each represent wherein A is carboxyl, T is CN, F or Cl and p=0 or 1, provided that when T is F or Cl x has a value of at least 2.
