ABSTRACT
We designed and synthesized a strong fluorescent tetradentate pyridine ligand, 3,6,11,12-tetra(pyridin-4-yl)dibenzo[a,c]phenazine (TPDP), by covalently grafting pyridyl to fluorescent dye dbpz, which can react with the Fe(NCX)2 (X = S and Se) unit, obtaining two new 2D [4 × 4] square-grid compounds, namely, {FeII(TPDP)2(SCN)2·CHCl3·4CH3OH}n (1) and {[FeII(TPDP)2(SeCN)2]·CH2Cl2·4CH3OH}n (2). Both of them show expected one-step spin-crossover (SCO) properties, and complex 2vacuum exhibits a combination of the SCO phenomenon and fluorescence in a synergetic way. The energy transfer mechanism of 2vacuum is verified by the theoretical calculations and experimental results. This study provides an effective strategy to synthesize large conjugated fluorescent ligands using dyes to further form SCO-luminescent bifunctional materials.
