Chirogenesis and Pfeiffer Effect in Optically Inactive Eu^III and Tb^III Tris(β-diketonate) Upon Intermolecular Chirality Transfer From Poly- and Monosaccharide Alkyl Esters and α-Pinene: Emerging Circularly Polarized Luminescence (CPL) and Circular Dichroism (CD).

ABSTRACT: We report emerging circularly polarized luminescence (CPL) at 4f-4f transitions when lanthanide (Eu^III and Tb^III) tris(β-diketonate) embedded to cellulose triacetate (CTA), cellulose acetate butyrate (CABu), D-/L-glucose pentamethyl esters ( D-/ L-Glu), and D-/L-arabinose tetramethyl esters ( D-/ L-Ara) are in film states. Herein, 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionate (fod) and 2,2,6,6-tetramethyl-3,5-heptanedione (dpm) were chosen as the β-diketonates. The g _lum value of Eu(fod)₃ in CABu are +0.0671 at 593 nm (⁵ D 0 → 7 F₁) and -0.0059 at 613 nm (⁵ D 0 → 7 F
