A range of functionalized bis(phenyl-?-diketonato)titanium(IV) ethoxide complexes the type [Ti(L)2(OEt)2], containing two asymmetric or symmetric phenyl-?-diketonate ligands (L), have been synthesized and fully characterized. Single crystal X-ray diffraction has used to confirm that all structures crystallize with ancillary in a cis arrangement NMR spectra show characteristic ligand rearrangeme...

• Mechano-optics such as tribo/high-pressure luminescence is useful in stress sensing. First to explore the possibility of lanthanide complexes sensors. A new family halogen Eu III diketonate with unique optics examined. Shows influence crystal packing/high-pressure compression on triboluminescence. Diamond anvil cell show material induces phase transition/peak shifting. Triboluminescence and h...
