Our work made it onto the cover of Chemistry: A European Journal! In this paper, we describe the fusion of a naphthalene diimide dye (a family of well-known versatile light absorbing compounds) to a zinc–bis-salicylimide phenylene moiety (“salphen”, employed in catalysis and supramolecular chemistry) creates an expanded red-light absorbing chromophore with an embedded metal atom for interaction with substituted pyridines. A column-chromatography-free preparation of this novel scaffold is described and its photophysical properties are analyzed.
