New soluble dyes and insoluble organic pigments based on the diketopyrrolopyrrole skeleton have been prepared via Suzuki–Miyaura coupling on 3,6-bis(4-bromophenyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione. Boc protection of the amidic functions was advantageously used to solubilize the starting diketopyrrolopyrrole prior to the introduction of substituents. Absorption, fluorescence emission and optical
通过在3,6-双(4-溴苯基)吡咯并[3,4- c ]吡咯-1,4(2H,5H)-上的Suzuki-Miyaura偶联制备了基于二酮吡咯并吡咯骨架的新型可溶性染料和不溶性有机颜料。 dione。在引入取代基之前,对酰胺官能团的Boc保护有利地用于溶解起始的二酮吡咯并吡咯。介绍了这些新型二酮吡咯并吡咯染料的吸收,荧光发射和光学特征。
