Dichroic liquid crystal composition with 4,4-bis (substituted naphthylazo)azobenzene dichroic dyes |
| 摘要 |
Dichroic dyes of the 4,4'-Bis-(substituted naphthylazo)azobenzene type, each having three azo (-N=N-) bonding groups, provide a high order parameter in excess of 0.70, when dissolved in liquid crystal mixtures to provide contrast ratios on the order of 10:1.
