The successful applications of subphthalocyanines (SubPcs) in the field molecular materials largely stem from their unique post-functionalization versatility, where regioisomerism and substitution patterns play critical roles. In this context, chiral tritopic [Formula: see text]- or text]-symmetric SubPcs, as well more symmetric hexatopic C 3v have been extensively explored. However, derivatives with symmetry represent an appealing yet underexplored family, combining lower density former simplified latter. Herein, we explore triimide-SubPcs. Specifically, synthesize a versatile synthon based on triimide-SubPcs equipped iodoaryl groups. These SubPcs exhibit high sensitivity under typical reaction conditions employed for cross-coupling reactions, including Suzuki, Sonogashira, Buchwald-Hartwig protocols. Nonetheless, optimize Stille conditions, enabling selective installation ethenyl ethynyl substituents aryl groups attached to imide nitrogen atoms. UV-Vis absorption spectroscopy theoretical calculations reveal that do not significantly alter electronic structure SubPc macrocycle. Collectively, study establishes pathway toward synthesis unexplored highly promising family expanding toolbox advanced materials.
