Abstract
Ordered polymeric networks are produced via the photopolymerization of liquid-crystalline (LC) diacrylates. When these diacrylates are deriv ed from aromatic rings, the networks show UV-light instability. In ord er to overcome this problem, the cyclohexane analogues of two of these LC diacrylates were synthesized. The newly formed molecules exhibit m uch lower UV absorption than their aromatic analogues but also complet ely different phase behaviour. One of them showed a highly viscous LC phase, the other lacks LC properties.
