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 <sup>13</sup>C and <sup>15</sup>N NMR shifts correlate with <i>E</i> <sub>T</sub>(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.
