Regioisomerism is an important concept rarely discussed in organic electronics. The first structure–property relationship study of a key class of organic semiconductors—four spirobifluorene positional isomers—is reported. The impact of the ring bridging on the photophysical properties is stressed and the first member of a new family of spirobifluorenes substituted in the 1-position is described. This new compound presents better performance in blue phosphorescent OLEDs than those of its regioisomers. More information can be found in the Full Paper by C. Poriel et al. on page 7719.
