Insights into the Effect of Trans-to-Cis Photoisomerization of a Co-coordinated Stilbene Derivative on the Luminescence of Di-β-diketonate Lanthanide Complexes.

ABSTRACT: Five lanthanide complexes constructed from a stilbene derivative, (E)-N',N'-bis(pyridin-2-ylmethyl)-4-styrylbenzoyl hydrazide (HL), and two β-diketonates (2-thenoyltrifluoroacetonate, tta), with or without a trifluoroacetate anion (CF₃CO₂ ^-), namely, [Ln(tta)₂(HL) (CF₃CO₂)] [LnC₄₅H₃₂F₉N₄O₇S₂, Ln = La (1), Nd (2), Eu (3), or Gd (4)] and [Yb(tta)₂(L)] (YbC₄₃H₃₁F₆N₄O₅S₂ (5), L = deprotonated HL), were synthesized and characterized. Crystals of these five complexes were obtained and analyzed by single-crystal X-ray diffraction. These
