Synthesis and optical properties of antimony(V) complexes of a trianionic N < sub > 2 < /sub > O < sub > 2 < /sub > -type tetradentate dipyrrin ligand

Chem Commun (Camb). 2024 Apr 4. doi: 10.1039/d4cc00630e. Online ahead of print.ABSTRACTLSbCl2, an air- and moisture-stable antimony(V)-dipyrrin complex at room temperature, was obtained by treating an excess amount (20 eq.) of SbCl3 with a trianionic N2O2-type tetradentate dipyrrin ligand (L) under visible-light irradiation and O2 atmosphere. The Cl ligands in LSbCl2 were replaced by OH ligands via hydrolysis, yielding LSb(OH)2. Further, the molecular structures and optical properties of the Sb(V)-dippyrin complexes were investigated. While LSbCl2 was non-fluorescent, LSb(OH)2 exhibited an intense red fluorescence with a photoluminescence quantum yield of 68%.PMID:38572576 | DOI:10.1039/d4cc00630e
