    • Soluble poly(bis-9,9′-fluorenes) comprise identical or different structural repeating units of the formula I, where the two R1s are, independently of one another, H, C1-C18alkyl, C6-C14aryl, C7-C15aralkyl, C1-C18alkoxy, R2—(O—CnH2n)m—O—, C1-C18alkylthio, C1-C18dialkylamino, —C(O)OH, —C(O)O—C1-C18alkyl, —C(O)—N(C1-C18alkyl)2, —SO3H, —SO3—C1-C18alkyl, —SO2—N(C1-C18alkyl)2, C1-C17alkyl-C(O)—O— or C1-C17alkyl-C(O)—, R2 is H or C1-C12alkyl, n is from 2 to 6 and m is from 1 to 12. The polymers can be used either alone or in admixture with at least one additional fluorophore whose absorption band overlaps the emission band (fluorescent emission) of the polymer of the formula I as active radiative layer for light-emitting diodes, VDUs and display elements.
    • 可溶性聚(双-9,9'-芴)包含相同或不同的式I结构重复单元,其中两个R 1彼此独立地为H,C 1 -C 18烷基,C 6 -C 14芳基,C 7 -C 15芳烷基,C 1 -C 18烷基, (O-C n H 2n)m O - ,C 1 -C 18烷硫基,C 1 -C 18二烷基氨基,-C(O)OH,-C(O)O-C 1 -C 18烷基,-C(O) 2,-SO 3 H,-SO 3 -C 1 -C 18烷基,-SO 2 -N(C 1 -C 18烷基)2,C 1 -C 17烷基-C(O)-O-或C 1 -C 17烷基-C(O) - ,R 2为H或C 1 -C 12烷基,n为2-6,m为1至12.聚合物可单独使用或与至少一种另外的荧光团混合使用,其吸收带与式(I)的聚合物的发射带(荧光发射)重叠 我作为发光二极管,VDU和显示元件的有源辐射层。
