Indenofluorene‐extended tetrathiafulvalenes connected to an electron acceptor moiety present a new promising class of chromophores for dye‐sensitized solar cells. Construction of the new donor‐acceptor scaffolds relied on a Sonogashira coupling as the key synthetic step. A dye‐sensitized solar cell constructed from a compound containing a benzothiadiaziole acceptor exhibited good power conversion efficiency.
