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.

配位饱和镧系配合物对配体场对溶剂化和供体极化性的灵敏性†

一系列C ₃对称，九配位的吡啶基三氮杂环壬烷Yb（III）和Eu（III）配合物的晶体学，发射光谱和NMR研究表明，局部溶剂化和配体偶极极化率对配体场强的影响，导致剧烈变化在伪接触式NMR位移和发射光谱图中的应用，为响应式NMR和光谱探针设计提供了新的指导。
