摘要：

In a series of organometallic azobenzene Pd(II) complexes, which are of interest as mesogenic materials, cyclopalladation blocks the azo group in the trans configuration. Whereas the uncomplexed azobenzene reference compound is not luminescent, the complexes are weakly luminescent (phi similar to 10(-4), tau=1-3 ns) owing to the emissive properties of n pi* excited states localized on the trans-blocked azobenzene ligand. These findings suggest that cyclopalladated ate-containing compounds may afford luminescent liquid crystalline materials.
