[4,4′-Bis(4-fluorophenyl)-6,6′-dimethyl-2,2′-bipyridine] [bis (2-(diphenylphosphino) phenyl) ether] Silver(I) Hexafluorophosphate
Round 1
Reviewer 1 Report
This article of Glycos et al. reports the synthesis and characterziation of a new emissive heteroleptic Ag(I) complex. While the spectroscopic characterziation of this complex in solution is not extensive (no IR, 31P and 13C NMR), the author bring sufficient evidence for its formation by reporting its solid state structure. Further studies reveal that the compound is a yellow-green phosphor (at 528 nm), with moderate quantum efficiency in deaerated DCM solution (ΦP = 25%), significantly better than its known 2,2’-bipyridine analogue in solution, but with a BF4- counter anion rather than PF6- (5%). While exploring the impact of solvent and counter anion on the phosphorescence quantum yield of such complexes would have brought some useful iadditional information, I nevertheless recommend publication of this work in Molbank provided the few typos listed hereafter are corrected.
Typos/suggestions:
Line 46: “[PF6]”, put “6” in subscript.
Line 72: Stokes shifts are usually given in energy units (cm-1) rather than in nm.
Line 137: Intermolecular pi-pi* interaction (rather than intramolecular).
Line 206: “1H NMR” (1 in superscript)
