A new isophorone-based ligand and its Ag(I) complex: crystal structures and luminescence

Abstract

<div><p>An isophorone-based ligand with a delocalized π-electron system, 2-{5,5-dimethyl-3-[2-(pyridine-4-yl)ethenyl]cyclohex-2-enylidene}propanedinitrile (<b>L</b>), was synthesized. By assembling the ligand with AgNO₃, a mononuclear complex [Ag(L)₂]NO₃·H₂O was obtained. Compared with the free ligand, the complex shows superior luminescent properties with large red-shift and longer fluorescence lifetime.</p></div
