Perylene-3,4:9,10-tetracarboxylic-3,4-anhydride-9,10-imides have been transformed in one-step into bichromophoric 9,9′-bis(perylene-3,4-dicarboximide)s by reaction with copper powder, 3-methylpyridine, and oxygen, and further to quaterrylene bisimides with potassium tert-butoxide and DBN. Quaterrylene bisimides are of interest as NIR fluorescent dyes.
通过与铜粉、3-甲基吡啶和氧气反应,一步法将苝-3,4:9,10-四羧酸-3,4-酸酐-9,10-酰亚胺转化为双色 9,9′-双(苝-3,4-二甲酰亚胺),并与叔丁醇钾和 DBN 反应进一步转化为季戊二烯双酰亚胺。四季烯双亚胺作为近红外荧光染料具有重要意义。
