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.
