Dimerization of the so-called pyrrolopyrrole aza-BODIPY, which is a new class of aza-BODIPY analogues exhibiting intense absorption and emission in the visible (Vis) and near infrared (NIR) region, via a bithienyl linkage led to the creation of a novel black dye with dual emission and panchromatic absorption properties in the Vis/NIR region. The role of the linkage in the dye was unambiguously elucidated by comparison of the optical properties with those of its biphenyl-linked counterpart.

通过简单的二聚化使aza-BODIPY类似物变黑：吡咯并吡咯aza-BODIPY二聚体的全色吸收†

所谓的吡咯并吡咯aza-BODIPY的二聚体是一类新型的aza-BODIPY类似物，通过二噻吩基键合在可见（Vis）和近红外（NIR）区域表现出强烈的吸收和发射，从而导致了在Vis / NIR区域具有双重发射和全色吸收特性的新型黑色染料。通过将光学性质与其联苯基连接的对应物的光学性质进行比较，明确阐明了该键在染料中的作用。
