The synthesis and characterization of a fluorene-spirobifluorene alternating copolymer, P(OF-SBF), are described. In the case of the spiro-segment, the two fluorene rings are orthogonally arranged and connected through a tetrahedral bonding carbon atom (t

(Chemical Equation Presented) Pure 2,2′-Dibromo-9,9′- spirobifluorene was synthesized by a method that did not involve troublesome dibromination of 9,9′-spirobifluorene or Sandmeyer reaction of 2,2′-diamino-9,9′-spirobifluorene. A series of donor-acceptor orthogonally substituted 9,9′-spirobifluorene was subsequently prepared showing rich variation of fluorescence in solution and in solid state.
