Giant Enhancement of Second Harmonic Generation Accompanied by the Structural Transformation of 7‐Fold to 8‐Fold Interpenetrated Metal–Organic Framework (MOF)
“A baby cheetah leaps several feet more than the cheetah mom” is an old saying in Tamil. In this case, an 8‐fold interpenetrated MOF shows a giant enhancement of the second harmonic generation (SHG) as compared to the parent 7‐fold interpenetrated MOF. As shown in the Research Article (DOI: https://doi.org/10.1002/anie.20191163210.1002/anie.201911632) by R. E. Dinnebier, Q.‐H. Xu, J. J. Vittal et al., the 8‐fold interpenetrated MOF results from the removal of DMF from the channel in a single‐crystal‐to‐single‐crystal transformation.
