摘要

布鲁克的merocyanine染料的系统NMR/UV-Vis分析揭示溶剂极性支配电子结构和光谱。吸收最大13C和15N NMR位移与ET（30）相关，探测两性离子/葡萄酰胺。取代基和溶剂效应调节这些相互作用，直接将颜色变化与电子结构联系起来，以合理设计环境敏感探针。

An NMR insight into the solvatochromic behaviour of Brooker's merocyanine dyes†

Systematic NMR/UV-Vis analysis of Brooker's merocyanine dyes reveals solvent polarity governs electronic structure and spectroscopy. Absorption maxima ¹³C and ¹⁵N NMR shifts correlate with E_T(30), probing zwitterionic/vinylogous amide. Substituent and solvent effects modulate these interactions, directly linking colour changes to electronic structure for rational design of environment-sensitive probes.
