Embodiment 1
[0068] In the copolymer (I1) containing fluorene and thiophene pyrrole diketone units of this embodiment, R 1 , R 2 , R 3 Both are methyl, R 4 , R 5 , R 6 , R 7 All are H, x=1 / 4, y=3 / 4, n=20, and its structural formula is as follows:
[0069]
[0070] The copolymer represented by the above structural formula (I 1 ), R 4 , R 5 , R 6 , R 7 Both are H, indicating that compounds C and D have the same structure, so only one raw material needs to be provided, which not only simplifies the source of raw materials, but also improves the reaction yield.
[0071] The copolymer of the present embodiment (I 1 ) preparation comprises the following specific steps:
[0072] 1. The preparation of 2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxabororyl)-9,9-dimethylfluorene, i.e. compound A A specific example, its structural formula is as follows:
[0073]
[0074] The specific preparation process is as follows: Add 20.00mL (1.00M) n-butyllithium solution to a solution containing 3....
Embodiment 2
[0093] The copolymer (I 2 ), R 1 , R 2 , R 3 Both are C 8 h 17 ,R 4 , R 5 , R 6 , R 7 All are H, x=1 / 2, y=1 / 2, n=44, and its structural formula is as follows:
[0094]
[0095] Similar to Example 1, the copolymer represented by the above structural formula (I 2 ), R 4 , R 5 , R 6 , R 7 Both are H, indicating that compounds C and D have the same structure, so only one raw material needs to be provided, which not only simplifies the source of raw materials, but also improves the reaction yield. Moreover, R 1 , R 2 , R 3 and R 8 , R 9 Both are C 8 h 17 , which can improve the copolymer (I 2 ) molecular weight, which is conducive to processing and forming a film, for example, it is convenient for the copolymer to form a film by spin coating technology.
[0096] The copolymer of the present embodiment (I 2 ) preparation comprises the following specific steps:
[0097] One, the preparation of 2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolyl)-9,9-dioctylfluor...
