Electrooptical guest-host effect

Most of the electrooptic effects are based on light scattering or on light absorption by polarizers or by dissolved dyes. Electrooptic effects which belong to the second group are tunable birefringence, the twisted nematic effect and the guest-host effect. [Pg.61]

A combination of two dyes (with positive and negative dichroism) has been used [177] for color switching in the guest-host effect. The degree of dye order was 5dye = 0.677 and 0.754 for anthraquinone D /D > 1) and tetrazine (T) /D ) dyes, respectively. High values of color contrast were thus achieved on electrooptical switching. [Pg.189]
