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.
