For inserting enantiopure bi- and tridentate N-donors (1LR/1LS 2LR/2LS) into the precursor Eu(hfac)3(H2O)2 to replace two H2O molecules, respectively, pairs of chiral eight- nine-coordinate EuIII enantiomers Eu(hfac)3(1LR)/Eu(hfac)3(1LS) (D-1/L-1) Eu(hfac)3(2LR)/Eu(hfac)3(2LS) (D-2/L-2) were isolated, in which hfac- = hexafluoroacetylacetonate, 1LR/1LS (-)/(+)-4,5-pinene-2,2'-bipyridine, 2LR/2LS (-)/(+)-2,6-bis(4',5'-pinene-2'-pyridyl)pyridine. Compared with Eu(hfac)3(H2O)2, enantiomeric not only show significant improvements their photophysical performances but also display highly boosted third-harmonic generation (THG) effects, THG strengths D-1/L-1 D-2/L-2 are more than 14 27 times that respectively. Especially, D-2 L-2 symmetric have strong while D-1 L-1 asymmetric bidentate simultaneously hold SHG (second-harmonic generation) responses. More notably, from eight-coordinate L-1, further L-2, present successive considerable enhancements as degrees π-electron conjugation ligands continue rise. Furthermore, circularly polarized luminescence (CPL) properties examined.
