Luminescent polymers having doubly- or multiply-bridged biphenylene repeat units are provided, which are particularly suited as electroluminescent polymers. Monomers necessary for the synthesis of the multiply bridged biphenylene polymers are provided, as are electroluminescent devices utilizing these polymers.
