The structures of these DIAR couplers were indentified by IR-spectra H-NMR-spectra, elemental analysis, and Mass-spectra Good effect was obtained in the applied experiment of the DIAR couplers.

• 以黄成色剂为DIAR成色剂的母体,以取代的苯酚和取代的硫酚分别作为定时基团,取代的四氮唑、噻二唑和苯骈三氮唑为抑制基团合成了5个新的DIAR成色剂,并通过红外、核磁、质谱和元素分析对它们的结构进行了表征。
