The selective iodination of 2,7,12,17-tetrahexylporphycene 1 was successfully accomplished by using N-iodosuccinimide in the presence of activators to give 3-iodoporphycene 2 and 3,13-diiodoporphycene 3a. These iodinated porphycenes can be used as the substrates for palladium-catalyzed coupling to prepare porphycene-diketopyrrolopyrrole conjugates in two steps. The connection of the diketopyrrolopyrrole units to porphycenes broadened their absorption spectra and increased the intensity of the Q-bands due to the electronic interactions between the porphycene and diketopyrrolopyrrole moieties.
通过在活化剂存在下使用N - 碘代琥珀酰亚胺，成功实现了2,7,12,17 - 四己基卟啉1的选择性碘化，得到3 - 碘代卟啉2和3,13 - 二碘代卟啉3a。这些碘化卟啉可用作钯催化偶联的底物，分两步制备卟啉 - 二酮吡咯并吡咯共轭物。由于卟啉和二酮吡咯并吡咯部分之间的电子相互作用，二酮吡咯并吡咯单元与卟啉的连接拓宽了它们的吸收光谱并增加了Q带的强度。
