Heteroleptic zinc dipyrromethene complexes
Amiri, A., IM Comeau, and A. Thompson. 2006. "Heteroleptic zinc dipyrromethene complexes." Journal of Heterocyclic Chemistry 43(2): 431-435.H-1 NMR spectroscopy has been used to study the complexation of a per-alkyl dipyrromethene with zinc acetate. An intermediate, assigned to be the heteroleptic Zn(dipyrromethene) (acetate) complex, is observed under titration ... -

Self-assembly of novel trimers using dipyrromethene ligands
Thompson, A., SJ Rettig, and D. Dolphin. 1999. "Self-assembly of novel trimers using dipyrromethene ligands." Chemical Communications: 631-632.Ligands comprising two dipyrromethene units linked at the beta-position have been used to prepare trimeric complexes with Zn-II and Co-II; the structure of the Zn-II complex is confirmed by X-ray analysis.
