Variations in the electromagnetic wavelengths of absorption and reflection of molecules do not only make life colorful but also are often of central importance in solar energy conversion and optoelectronic information processing and transfer. Dithizone and its derivatives and complexes are, to our knowledge, probably the most “colorful” compound, being responsive to no less than seven different external stimuli that effect color change. Apart from a more detailed discussion of the cyclic voltammetry and observed electrochromism in the SCH3-substituted free ligand and mercury complex, concentratochromism, solvatochromism, halochromism, thermochromism, and chronochromism in the ligand, and photochromism in the carboxy-functionalized phenylmercury(II) complex are also presented here. Color changes are either associated with proton transfer or loss, or isomerization.

与双硫zone有关的七种色度

分子吸收和反射的电磁波长的变化不仅使生活变得丰富多彩,而且在太阳能转换以及光电信息处理和传递中通常也至关重要。据我们所知,双硫zone及其衍生物和配合物可能是最“有色”的化合物,对至少七种影响颜色变化的外部刺激有反应。除了更详细的讨论循环伏安法和观察到的SCH 3中的电致变色取代的游离配体和汞络合物,配体中的集中变色,溶剂变色,卤致变色,热致变色和变色现象,以及羧基官能化的苯基汞(II)络合物中的光致变色。颜色变化与质子转移或损失或异构化有关。
