Meso-meso directly linked dipyrrolyl ligand dimer that shows the formation of metal-coordination polymers

摘要

A novel dipyrrolyl metal-coordination ligand dimer directly connected at the meso positions showed the formation of a Zn~(II)-bridged coordination polymer and the spontaneous transformation to a meso-meso- and singly β-β-fused tetrapyrrolyl molecule in solution by C-C bond formation and concomitant proton migration.
