From local to global or semilocal aromaticity: singlet-triplet switching in porphyrin tapes [0.03%]
从局部到全局或半局部芳香性:卟啉带单重态-三重态切换
Sergio Moles Quintero,Luis Álvarez-Thon,William Tiznado et al.
Sergio Moles Quintero et al.
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 po...
Selective etching of binary nanoparticle superlattices via thermally induced asymmetric ligand evolution [0.03%]
