Magnetic and electronic analyses reveal aromaticity transitions in porphyrin tapes, suggesting new electronic properties.
Magnetic and electronic analyses of porphyrin tapes uncover a transition from local aromaticity in the ground state to extended/semilocal aromaticity in the triplet state. This reorganization reduces the singlet-triplet gap, establishing porphyrin tapes as aromatic chameleons with state-dependent electronic structures and magnetic responses.
