properties. The selective synthesis of unsymmetrical systems, particularly phthalocyanines, has remained a significant unmet challenge. Porphyrin‐phthalocyanine hybrids offer the potential to combine the favorable features of both parent structures, but again synthetic strategies are poorly developed. Here we demonstrate strategies that give straightforward, controlled access to differentially substituted

Up to now, hybrid structures that lie between the ubiquitous phthalocyanine and porphyrin scaffolds have been extremely difficult to prepare. A straightforward, high‐yielding synthesis of meso‐derivatized tetrabenzotriazaporphyrins (see scheme) is described, thus unlocking access to this underdeveloped class of materials.

The first syntheses of hybrid structures that lie between subphthalocyanines and subporphyrins are reported. The versatile single‐step synthetic method uses a preformed aminoisoindolene to provide the bridging methine unit and its substituent while trialkoxyborates simultaneously act as Lewis acid, template, and provider of the apical substituent. The selection of each component therefore allows for
