    • A process for the preparation of a conjugated poly(arylene vinylene) copolymer for use in a luminescent device, which comprises: (1) providing a precursor polymer comprising units of general formula in which Ar is substituted or unsubstituted arylene, L is a leaving group, R1 and R2 are each independently H, alkyl, alkoxy, aryl or an electron-withdrawing group, and n is an integer; (2) reacting the precursor polymer with a reactant comprising a carboxylate, an aldehyde, a ketone, a sulphonate, a thioate, a disulphide, a xanthate, an amine, a pyridine, a hydrazide, a phenoxide, an alcohol with a boiling point above 100° C., or a derivative thereof, under substitution conditions whereby a proportion of the leaving groups are substituted to form a substituted precursor copolymer comprising units of general formula in which Ar, R1, R2 and L are defined above, X is a substituent group from the reactant, l and m are independently integers; and (3) converting the substituted precursor copolymer to a conjungated poly(arylene vinylene) copolymer by elimination of the leaving groups from the substituted precursor copolymer.
    • 一种制备用于发光装置的共轭聚(亚芳基亚乙烯基)共聚物的方法,其包括:(1)提供包含一般结构单元的前体聚合物,其中Ar为取代或未取代的亚芳基,L为离去基团, R1和R2各自独立地为H,烷基,烷氧基,芳基或吸电子基团,n为整数; (2)使前体聚合物与包含羧酸盐,醛,酮,磺酸盐,硫酸盐,二硫化物,黄原酸盐,胺,吡啶,酰肼,酚盐,沸点的醇的反应物反应 100℃以上的衍生物或其衍生物,其中一部分离去基团被取代以形成包含通式如下的取代的前体共聚物,其中Ar,R 1,R 2和L如上定义,X​​为取代基 反应物组,l和m独立地为整数; 和(3)通过从取代的前体共聚物中消除离去基团将取代的前体共聚物转化为连接的聚(亚芳基亚乙烯基)共聚物。
