| 摘要 |
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): wherein: Ar1 and Ar2 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; Q1 and Q2 are independently selected from the group consisting of H, aryl, heteroaryl, substituted aryl, substituted heteroaryl, alkyl, and substituted alkyl, and Q3 is selected from the group consisting of alkyl and substituted alkyl, with the proviso that when m is 1, Q1 and Q2 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. |
