Shades of violet: The nitrogen‐free homologues of perylene tetracarboxylic diimide dyes have been prepared. CsOH succeeds where KOH fails to couple sterically demanding hydroxyphenalenones into the esterifiable precursors of π‐stacking long‐wavelength absorbing disks (see figure).
紫罗兰色:已制备了tetra四羧酸二亚胺染料的无氮同系物。如果KOH无法将空间需求的羟基苯乙酮耦合到π堆积长波长吸收圆盘的可酯化前体中,则CsOH会成功(见图)。
