A series of new dispiro[fluorene-9′,6,9′′,12-indeno[1,2b]fluorenes] (DSFIFs) that combine indenofluorene (IF) and spirobifluorene (SBF) architectural specificities have been prepared. Their anodic oxidations lead to the formation of nonsoluble transparent polymers. The photophysical and electrochemical properties of these new molecules have been evaluated for further blue OLED applications. Poly-2,7-(9,9-dialkyl)fluorenes (PFs) and copolymers are among the most promising blue light emitting materials despite the problem of their long-term color stability.
