这项研究提出了多种包含两个质子转移链段(邻羟基苯基亚氨基)的AB2型新型目标染料。此外,还提供了不存在羟基或亚氨基的相应参考分子。目标染料中的双分子内氢键由1表示1 H NMR光谱,X射线单晶分析以及单光子吸收光谱。在各种介质(例如有机溶剂,固相状态以及PMMA底物)中确定这些目标染料和参考染料的线性发射特性(静态和瞬态发射特性)和双光子吸收光学特性。结果表明,新型AB2型目标染料在单光子辐照和近红外飞秒激光双光子辐照下分别能在激发态下有效地进行内质子转移,从而表现出良好的双发射分离。进行分子几何优化以分析目标AB2发色团在激发态下内部质子转移的发生。

A method of making a holographic data storage medium is provided. The method comprises: (a) providing an optically transparent substrate comprising at least one photochemically active dye; and (b) irradiating the optically transparent substrate at least one wavelength at which the optically transparent substrate has an absorbance in a range from about 0.1 to 1, to produce a modified optically transparent substrate comprising at least one optically readable datum and at least one photo-product of the photochemically active dye. The at least one wavelength is in a range from about 300 nanometers to about 800 nanometers. The optically transparent substrate is at least 100 micrometers thick, and comprises the photochemically active dye in an amount corresponding to from about 0.1 to about 10 weight percent based on a total weight of the optically transparent substrate.
