Effect of charge-transfer acceptors on dynamic scattering in a nematic liquid crystal

Abstract

The addition of charge‐transfer acceptors to a nematic liquid crystal at concentrations <0.1% has a profound effect on the voltage‐transmission characteristics for dynamic scattering, reducing the threshold voltage by a factor of 2 for dc fields, but not appreciably altering the ac behavior. Charge‐transfer bands in the visible may be introduced that depend on the concentration and nature of the acceptor molecule employed.
