The spectroscopic properties, transient spectra and kinetics of a composite molecule are described. This molecule consists of a photochromic moiety chemically bonded to a strongly fluorescing dye. Experimental data presented here show that this composite molecule performs as an erasable, re-writable molecular optical storage medium with non-destructive read-out. The dependence of the fluorescence efficiency on the structure of the photochromic group and viscosity is discussed.
本文描述了一种复合分子的光谱特性、瞬态光谱和动力学。该分子由一个光致变色分子和一个强荧光染料化学键合而成。本文提供的实验数据表明,这种复合分子可作为一种可擦除、可重写的分子光学存储介质,并具有非破坏性读出功能。本文讨论了荧光效率与光致变色基团结构和粘度的关系。
