Synthesis and Characterization of Novel Fused Porphyrinoids Based on Cyclic Carbazole[2]indolones

The carbazole- and indolone-based porphyrinoids 3 and 4 were synthesized by stepwise transition-metal-catalyzed coupling reactions. Palladium metalation of 4 produced 4Pd, which exhibits near-infrared absorption.以咔唑（carbazole）和吲哚酮（indolone）为骨架的卟啉类衍生物（porphyrinoids）3与4，通过逐步过渡金属催化偶联反应合成得到。对化合物4进行钯金属化反应可得到4Pd，该产物具有近红外吸收特性。
