The structure with fused aromatic ring is of formula (6).A, D=direct bond, -O-, -S-, -CO-, -SO2-, -SO-, -CONH-, -COO-, -(CF2)i-, -(CH2)j, -CR'2-, cyclohexylidene or fluorenylidene;i=1-10;j=1-10;R'=aliphatic hydrocarbyl, aromatic hydrocarbyl ort halogenated hydrocarbyl;B=O or S;R1-R16=halogenoalkyl, allyl, aryl, nitro, nitrile, H, F or optionally halogenated alkyl;s, t=0-4; andr=0 or 1.The polyarylene has a structure of formula (8). EXAMPLE - 3-(2,5-Dichlorobenzoyl)benzenesulfonic acid neopentyl ester (37.6 g), N,N-dimethylacetamide (166 mL), compound with polyarylene structure (13.4 g), 3-(2, 5-dichlorobenzoyl)pyridine (1.18 g ) were added to bis(triphenylphosphine) nickel dichloride, (2.62 g), triphenylphosphine (10.5 g), sodium iodide (0.45 g) and zinc (15.7 g) under nitrogen atmosphere. Next, the reaction system was heated while stirring to 82 degrees C and reacted for 3 hours. The reaction solution was diluted with N,N-dimethylacetamide (175 mL), stirred for 30 minutes, and filtered with cerite. The filtrate was divided into 3 parts and added one at a time to lithium bromide (24.4 g) at intervals of 1 hour, reacted under nitrogen atmosphere at 120 degrees C for 5 hours, cooled to room temperature, poured into acetone (4 L) and coagulate. The solidified substance was filtered, air dried, washed with 1500 mL of 1N sulfuric acids, filtered, washed with ion exchange water and dried at 80 degrees C forming the polymer.
