Among the plethora of polycyclic structures that have emerged in recent years, indenofluorenes comprise a unique class of com pounds due to their potential in organic electronic systems such as OLEDs, OFETs, and OPVCs. However, the synthesis of fully conjugated indenofluorenes without bulky groups on the apical carbons under standard chemistry conditions is not easily acces sible. In this regard, on-surface synthesis has appeared as a newly developing field of research, which exploits the use of well-defined solid surfaces as confinement templates to initiate and develop chemical reactions. Here, we demonstrate the successful fabrica tion of indeno[1,2-b]fluorene p-conjugated polymers linked via cumulene-like connections on well-defined metallic surfaces under ultra-high vacuum conditions.
