Crystallographic, emission and NMR studies of a series of C3-symmetric, nine-coordinate substituted pyridyl triazacyclononane Yb(iii) and Eu(iii) complexes reveal the impact of local solvation and ligand dipolar polarisability on ligand field strength, leading to dramatic variations in pseudocontact NMR shifts and emission spectral profiles, giving new guidance for responsive NMR and spectral probe design.
一系列具有 C3 对称性的、九配位取代吡啶三氮杂环壬烷 Yb(iii) 和 Eu(iii) 配合物的晶体学、发射和 NMR 研究揭示了局部溶剂化和配体偶极极化率对配体场强度的影响，导致赝接触 NMR 位移和发射光谱轮廓的剧烈变化，为响应性 NMR 和光谱探针设计提供了新的指导。
