TL;DR: In this article, the polymerizable liquid-crystalline compounds of the general formula (I) Z?1-Y1-A 1-Y3-M-Y4-A2-Y2-Z2? in which the variables have the following meanings: Z1, Z2 are radicals with reactive groups which can bring about polymerization; Y1 - Y4 are a chemical single bond, oxygen, sulphur, -O-CO-, -CO-O-, -OCO-N, -NR-CO-NR-, or -NR

TL;DR: In this paper, the general formula (I) Z-Y-A-Y -A-S, COO, OCO, CONR or N(R)CO was proposed for cholesteric liquid crystals.

TL;DR: PolyPolymerisierbare chirale Verbindungen der allgemeinen Formel as mentioned in this paper haben a folgende Bedeutung haben A Spacer, M mesogene Gruppen Y 1,Y 2 chemische Bindungen.

TL;DR: Polymerisierbare flussigkristalline Verbindungen der allgemeinen Formel (I): Z1, Z2 Reste with reaktiven Gruppen, uber die eine Polymerisation herbeigefuhrt werden kann, Y1 - Y4 chemische Einfachbindung, Sauerstoff, Schwefel, -O-CO-, -CO-O-, -O-, CO-N-, -NR-CO-NR-, -N-NR-O- or -NR

TL;DR: In this paper, a wafer-like multilayer cholesteric pigment, characterised by the layer sequence A1/B/A2, was introduced, where A stands for at least one intermediate layer which separates layers A?1 and A2? and fully or partially absorbs the light that passes through them.
