Rigid, yet flexible: formation of unprecedented silver MB-DIPY dimers with orthogonal chromophore geometry

Dalton Trans. 2020 Apr 28;49(16):5034-5038. doi: 10.1039/d0dt00927j.

Abstract

The reaction between MB-DIPY sodium salts and Ag(i) ions results in the formation of unprecedented MB-DIPY2Ag2 dimers in both solution and the solid state. These dimers have a short Ag-Ag contact (∼2.9 Å) and orthogonal twist in each of the MB-DIPY chromophores. The electronic structure of the unique dimers was probed by spectroscopic and theoretical methods.
