Figure 3.

Transition dipole moment magnitudes (μ) of pristine and substituted Cy5 dyes. The given substituent groups are placed on R₁ and R₁’ sites in Figure 1. Geometry optimizations and excited state calculations were performed using the M06-2X functional. The dyes are grouped according to substituent classification and ordered by increasing μ. The lines added to the data are to highlight the trends of the data and are not meant to infer a quantitative behavior.
