  花青染料/层状钛酸盐插层化合物中的可见光诱导电子转移和长寿命电荷分离状态

  摘要：

  在花青染料/层状钛酸盐插层化合物中证明了可见光诱导的客体-主体电子转移和长寿命电荷分离态的形成。1,1'-Diethyl-2,2'-cyanine (dye-1) 和 5,5'-dichloro-3,3',9-triethyl-thiacarbocyanine (dye-2) 嵌入层状钛酸盐 CsxTi2-x /4□x/4O4（□=空位，x=0.7）和Na2Ti3O7，通过阳离子交换反应，以烷基铵交换形式为中间体。通过 XRD、元素分析以及可见光吸收和荧光光谱证实了插层化合物的形成。对于所有染料/钛酸盐体系，嵌入的染料在层间空间中形成 J-聚集体。可见光诱导的电子转移表现为 ESR 信号的出现，这归因于染料的自由基阳离子，并通过染料聚集体的荧光猝灭。从 ESR 信号的衰减曲线估计电荷分离状态的表观寿命。字符...

  A color correction filter with excellent durability is provided that can remove intermediate colors of light while preventing brightness of an image display from deteriorating and thereby can improve color tone representation of the image display. A color correction filter 10 of the present invention includes a color correction layer 11 and two protective layers 12 . The color correction layer 11 contains a J aggregate of a dye. The dye is at least one dye selected from the group consisting of cyanine, merocyanine, squarylium, and porphyrin. The half bandwidth at a maximum absorption peak of the color correction layer is in the range of 5 to 30 nm. The two protective layers 12 are formed on both surfaces of the color correction layer 11 , respectively.
