Figure 8
A two-dimensional descriptor for assessing SF candidates. The thermodynamic driving force for SF (Es − 2Et) is displayed on the x axis and the singlet exciton charge-transfer character (%CT) is displayed on the y axis. The error bars correspond to the range of %CT values obtained by using different hole positions when performing the double-Bader analysis. Compounds I and VI (the latter highlighted in red) are com­pared to some acene and rylene phases.
