文摘

With the aim of combining luminescence and chirality in heterometallic Ir(III)鈥揅d(II) coordination networks, synthetic strategies for the formation of new Ir(III)-based chiral metallatectons ([Ir(dFppy)₂(1)][PF₆]), both as a racemic mixture of 螖 and 螞 enantiomers (rac-[Ir(dFppy)₂(1)][PF₆]) and as enantiopure complexes (螖-[Ir(dFppy)₂(1)][PF₆] and 螞-[Ir(dFppy)₂(1)][PF₆]), were developed. The final compounds were characterized both in solution and in the crystalline phase. Notably, their crystal structures were determined by single crystal X-ray diffraction, and their photophysical properties in solution and in the solid state were investigated. Combination of the cationic linear metallatecton with Cd²⁺ iodide salt ([CdI₃]^{鈭?/sup>), behaving as an anionic two-connecting node, leads to the formation of 1D chiral and neutral heterometallic Ir(III)鈥揅d(II) luminescent coordination networks both as a racemic mixture and as enantiomerically pure infinite architectures. The latter have been structurally studied in the solid state by X-ray diffraction both on single crystals and on microcrystalline powders. The infinite coordination networks display phosphorescence in the solid state at ca. 600 nm upon excitation at 400 nm.}
