Corrigendum: Chirogenesis and Pfeiffer Effect in Optically Inactive EuIII and TbIII 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)

A Corrigendum on
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)

In the original article, there were mistakes in Table 1 as published. Table 1 aimed to compare all g_lum values at specific wavelengths of four Ln^III tris(β-diketonates) (Ln^III: Eu^III and Tb^III) upon intermolecular chirality transfer from CABu, CTA, Glu (D- and L-), Ara (D- and L-), and α-pinene for clarity and readability. However, although the g_lum values described in the main text are correct, most data in the three right-side columns of Table 1 are incorrectly displayed. Also, in Table 1 caption, D-/L-glucose pentameyhyl esters should be D-/L-glucose pentamethyl esters. The corrected Table 1 with corrected numerical values in the three right-side columns and corrected caption appears below.

TABLE 1

Table 1. CPL characteristics (dissymmetry ratio, g_lum in 10⁻² at specific wavelength) of Eu^III and Tb^III coordinated with three β-diketonates as achiral ligands embedded in two polysaccharide alkyl esters (CABu and CTA), D-/L-glucose pentamethyl esters (D-/L-Glu), and D-/L-Arabinose tetramethyl esters (D-/L-Ara).

Also, there was an error in Introduction. The sentence starting with “Particularly, chirogenesis in metal coordination chemistry by the chirality transfer has long been one of the central subjects in inorganic chemistry 1 (Mason and Norman, 1965…)” should read as follows: “Particularly, chirogenesis in metal coordination chemistry by the chirality transfer has long been one of the central subjects in inorganic chemistry (Mason and Norman, 1965…)”.

The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
