Bis(dipyrrinato)zinc(II) Complexes: Emission in the Solid State

This Communication reports the first observation of solid-state photoluminescence in bis­(dipyrrinato)­zinc­(II) complexes with various substituents. The report discusses the effect of their substituents on their crystal structures and spectroscopic properties. Their meso-aryl groups are revealed to play important roles in the spectroscopic properties in the solid state.
