Abstract:
PCT No. PCT/EP96/05091 Sec. 371 Date May 29, 1998 Sec. 102(e) Date May 29, 1998 PCT Filed Nov. 19, 1996 PCT Pub. No. WO97/20877 PCT Pub. Date Jun. 12, 1997Soluble 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-C17-alkyl-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.
