Abstract:
Circularly polarized luminescence (CPL) activity was induced on a racemic Tb complex with a 1,4,7-triazacyclononane-based tris-phenoxide ligand by the coordination of a chiral 1-phenylethylamine ligand to the Tb centre. tert-Butyl groups at the ortho-position of the phenoxide moieties were found to be important for efficient CPL induction in the Tb complex.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
