    • An electroluminescent device having an anode and a cathode, one of which is transparent, and one or more organic layers between said anode and said cathode, at least one of said organic layers comprising an organic electroluminescent material, wherein at least one of said organic layers comprises a polymeric material having repeat units of Formula (1): wherein:Y 1 represents, independently if in different repeat units, N, P, S, As and/or Se, preferably N; Ar 1 and Ar 2 are aromatic groups and Ar 3 is present only if Y 1 is N, P, or As in which case it too is an aromatic group; wherein Ar 1 and Ar 2 are the same or different and represent, independently if in different repeat units, a multivalent (preferably bivalent) aromatic group (preferably mononuclear but optionally polynuclear) optionally substituted by at least one optionally substituted C 1-40 carbyl-derived groups and/or at least one other optional substituent; and Ar 3 represents, independently if in different repeat units, a mono or multivalent (preferably bivalent) aromatic group (preferably mononuclear but optionally polynuclear) optionally substituted by at least one optionally substituted C 1-40 carbyl-derived group and/or at least one other optional substituent, and wherein the average number, m, of said repeat units in the polymer is at least (35).
    • 一种具有阳极和阴极的电致发光器件,其中一个是透明的,并且在所述阳极和所述阴极之间的一个或多个有机层,所述有机层中的至少一个包括有机电致发光材料,其中至少一个所述有机层 包括具有式(1)的重复单元的聚合物材料:其中:Y 1独立地表示不同的重复单元,N,P,S,As和/或Se,优选N; Ar 1和Ar 2均为芳基,Ar 3仅在Y 1为N,P或As时存在,在这种情况下也为芳族基; 其中Ar 1和Ar 2相同或不同,独立地以不同的重复单元表示任选被至少一个任选取代的C 1 -C 6烷基取代的多价(优选二价)芳族基团(优选单核但任选多核) 40个碳基衍生基团和/或至少一个其它任选的取代基; 并且Ar 3独立地表示独立地以不同的重复单元表示任选被至少一个任选取代的C 1-40碳原子基团取代的单价或多价(优选二价)芳基(优选单核但任选多核)和/或 至少一个其它任选的取代基,并且其中聚合物中所述重复单元的平均数m至少为(35)。
