Structural characterization and optical properties of two copper(I)-iodide BODIPY coordination polymers

Abstract

Functionalization of boron-dipyrrin (BODIPY) chromophores with pyridine (1) or pyrimidine (2) substituents affords molecules with strong absorbance in the visible spectrum which are also highly fluorescent in solution, in thin films and as powders. Reaction of either 1, a bipyridyl ligand, or 2, a bipyrimidinyl ligand, with CuI in MeCN affords a one-dimensional coordination polymer (3) or a three-dimensional coordination polymer (4), respectively. Although the free ligands, 1 and 2, exhibit fluorescence in the solid-state, metal coordination in the CuI coordination polymers, 3 and 4, leads to quenching despite the retention of the BODIPY core.
