The invention provides conjugated polymers that have good solubility and semiconductivity, and that display high photoluminescent and electroluminescent efficiency. Representative polymers have the structure of formula (I):
1
wherein: Ar
1
and Ar
2
are independently selected from the group consisting of monocyclic, bicyclic and polycyclic arylene, heteroarylene, substituted arylene and substituted heteroarylene groups; L is alkylene, alkenylene, substituted alkylene, substituted alkenylene, heteroalkylene, heteroalkenylene, substituted heteroalkylene, substituted heteroalkenylene, arylene, heteroarylene, substituted arylene or substituted heteroarylene; m is zero or 1; n is zero or 1; Q
1
and Q
2
are independently selected from the group consisting of H, aryl, heteroaryl, substituted aryl, substituted heteroaryl, alkyl, and substituted alkyl, and Q
3
is selected from the group consisting of alkyl and substituted alkyl, with the proviso that when m is 1, Q
1
and Q
2
are other than H; and A
−
is an anionic counterion such as a halide ion. Electroluminescent and other devices containing a polymer of the invention are also provided.
该发明提供了具有良好溶解性和半导体性能,并具有高光致发光和电致发光效率的共轭聚合物。代表性的聚合物具有式(I)的结构:
其中:Ar1和Ar2分别选自单环、双环和多环芳基、杂芳基、取代芳基和取代杂芳基基团;L为烷基、烯基、取代烷基、取代烯基、杂烷基、杂烯基、取代杂烷基、取代杂烯基、芳基、杂芳基、取代芳基或取代杂芳基;m为零或1;n为零或1;Q1和Q2分别选自H、芳基、杂芳基、取代芳基、取代杂芳基、烷基和取代烷基,Q3选自烷基和取代烷基,但当m为1时,Q1和Q2不为H;A-是阴离子对离子,例如卤素离子。本发明还提供了含有该聚合物的电致发光和其他器件。
