摘    要:合成了1,5-二羟基-2-对烷氧基苯基蒽醌和1,5-二羟基-3-对烷氧基苯基蒽醌型黄色正性的二色性染料8个。1-氨基4-羟基-2-苯硫基蒽醌及1-氨基-4-羟基-2-苄氧基蒽醌红色正性的二色性染料2个。测定了染料分子在液晶中的有序参数,用CAMTC-ppp程序,计算了染料的跃迁能及染料分子的基态和激发态的偶极矩,发现染料分子在液晶中有序参数与染料分子基态和激发态偶极矩之间夹角θ有密切的关系。

关 键 词:染料  液晶显示  蒽醌染料  二色性染料  有序参数  彩色显示

Abstract:Eight positive yellow colour dyes, 1,5-dihydroxy-2,p-alkoxyphenylanthraquinone and 1,5-dihydroxy-3-p-alkoxyphenylanthraquinone type, and two red colour positive dyes, 1-amino-4-hydroxy-2-phenylthioanthraquinone and 1-amino-4-hydroxy-2-benzyloxyanthraquinone type were prepared. The order parameters of dye moleculars in liquid crystal were determined. The transition energy and dipole moment of dye molecules in ground and excited state were calculated with CAMTC-ppp procedure. The results show that the order parameter (S) of dye molecules in liquid crystal increases with the decrease of angles between dipole moments of molecules in ground and excited states.
Keywords:dyes  liquid crystal displays  anthraquinone dyes  dichroic dyes  order parameter  colour display
