An octupolar bis(porphyrinato) terbium(iii) complex with the highest off-resonant hyperpolarizability†
Abstract
A novel bis(porphyrinato) terbium double-decker complex HTb(DADAPor)2 with a twisted cuboid octupolar molecular symmetry exhibits the largest off-resonant first hyperpolarizability, as evaluated by harmonic light scattering measurements with = 1700 × 10−30 esu.
