    • A method for forming a polymer comprising the polymerization of a plurality of monomers, wherein at least one of the plurality of monomers is one or both of: a charge transporting unit and a hydrocarbon monomer in which at least one carbon atom has been substituted by an atom or group with a greater quantity of unshared valence electrons than the carbon atom it has been substituted for, and wherein at least one of the plurality of monomers comprises an end-capping compound at one end of said monomer, the end-capping compound preventing polymerization at the end, wherein the end-capping compound is not charge transporting and comprises at least two rings. The end capping compound preferably consists of or includes a structural unit having the formula: (Ar)n—X, wherein Ar in each occurrence independently represents an aryl or heteroaryl group; X represents a leaving group comprising a boron derivative group or halogen; and n is 2 or more.
    • 一种形成聚合物的方法,其包括多个单体的聚合,其中所述多个单体中的至少一个单体是以下之一或两者:电荷输送单元和烃单体,其中至少一个碳原子被 原子或基团,其具有比其已被取代的碳原子更大量的非共价价电子,并且其中所述多个单体中的至少一个单体包含在所述单体一端的封端化合物,所述封端化合物预防 末端聚合,其中封端化合物不是电荷输送并且包含至少两个环。 封端化合物优选包含或包括具有下式的结构单元:(Ar)n -X,其中Ar各自独立地表示芳基或杂芳基; X表示包含硼衍生物基团或卤素的离去基团; n为2以上。
