WebJul 6, 2024 · One Nd(III) complex [Nd 3 L 3 (OAc) 3] (1) was synthesized from a conjugate Schiff base ligand H 2 L. It shows a chiral "triple-decker" structure (1.1 × 1.2 × 1.8 nm) with Nd(III) ions sandwiched between the Schiff base ligands. 1 exhibits NIR Nd(III) luminescence, and the LMET efficiency is calculated to be 13.8%. It displays high ... WebThe Formula 2^(#centres) here, take the number of chiral centers i.e., differently asymmetric. In this Case as It's a cyclo-hexane ring, Both the 1 and 2 Bromo position are identical and thus there are only one pair of enantiomers.
