    Abstract: Provided are multilayer laminates having one or more layers comprising twisted nematic liquid crystals and one or more layers of a polymeric sheet. The twisted nematic liquid crystal layers reflect infrared radiation. Thus, the multilayer laminates are useful to reduce the transmission of infrared energy. For example, in some embodiments the multilayer laminates are useful as windows to reduce energy consumption necessary to cool the interior of a structure such as an automobile or building. Preferably, the multilayer laminates retain one or more of the beneficial properties of safety glass. The multilayer laminates may include additional layers such as infrared absorbing layers, half wave plates, and the like, to minimize the transmission of infrared energy. The multilayer laminates may also include further additional layers such as polymeric films, polymeric sheets, rigid sheets, and the like.

    Abstract: The invention relates to compounds of formula (I): wherein R1 and R2 are each independently selected from the group: H, F, Cl and CH3; n1 and n2 are each independently integers 3 to 20; q and r are each independently integers 0, 1 or 2, with the proviso that q+r is ≧1; D is a divalent chiral radical selected from the group: wherein R3 is a C1 to C6 straight or branched chain alkyl group; and each B1 and B2 is a divalent radical independently selected from the group: R4-substituted-1,4-phenyl, wherein R4 is H, —CH3 or —OCH3; 2,6-naphthyl; and 4,4′-biphenyl; with the provisos that when q+r=3, at least one of B1 and B2 is R4-substituted-1,4-phenyl; and when q+r=4, at least two of B1 and B2 are R4-substituted-1,4-phenyl. The invention further relates to liquid crystal compositions comprising compounds of formula (I) and polymer networks derived from the polymerization of the liquid crystal compositions.
