(a) General dithienylethene structure in open and closed form. (b) Pyridyl-functionalized dithienylethene derivative (DTE) highlighting atoms used in torsion angle measurements (blue), the distance between active carbons (Dactive) and distance between methyl groups (DMe–Me) (Mitchell et al., 2023BB13). (c) Plot of Dactive versus DMe–Me showing locations of the three distinct and populated regions. (d) One of the two photoactive compounds obtained with DTE.
