Nonalternant Acenaphthylene-Fused Carbaporphyrins: Topological Modulation of π-Delocalization, (Anti)aromaticity, and B <sup>III</sup> Coordination
Acenaphthylene (AN) fusion at the <i>meso</i>-position served as a structural and electronic modulator in carbaporphyrinoids, where the isomeric homocarbaporphyrinoids and their B<sup>III</sup> complexes remain nonaromatic due to electronic decoupling or nonplanarity. In contrast, the isolated [24]carbapentaphyrin(2.1.1.1.1) sustained global antiaromaticity. These findings confirm that AN fusion is an advantageous strategy for designing nonclassical porphyrinoid architectures with tunable (anti)aromatic properties.
