Abstract

In this review, we describe the syntheses and properties and application to liquid crystal displays（LCD）of liquid crystalline dendrimers（LD）having peripheral mesogenic units, which can be prepared by the reaction between a commercial polypropyleneimine dendrimer and acrylates having mesogenic units,and which exhibit spontaneous homeotropic orientation on glass. The effect of dendrimer generation, spacer length and mesogenic structure on the homeotropic orientation is also described. When LD（up to 1 wt％）are dissolved into nematic liquid crystals（NLCs）, this orientation can be induced to whole NLCs. A test cell with a combined mixture of LD and positive NLCs with a comb electrode can repeatedly switch between voltage-off dark and voltage-on bright states. The LD-induced homeotropic orientation could be applied to TFT liquid crystal display without using any polyimide alignment layers.
