Abstract

2,5-dialkyloxy-1,4-benzene is prepared by solid state oxidized coupling polymerization, which includes: selecting p-dialkyloxylbenzene as monomer with C1-18 in alkyloxyl and metal chloride as catalyst, mixing and abrasing at 5-65deg.C and reacting for 10-30 minutes to obtain the crude product, separating and purifying to get poly(2,5- dialkyloxyl-1,4-benzene). Because of no solvent in polymerization, it reduces environment pollution, lower production cost, short polymerization time of only 10-30 minutes to increase productivity, increasing polymerization yield up to 90%. The obtained product has good structure regional mapping orderliness. Between phenyl cycles there are chain connections of contraposition. The obtained polymer has a fluorescence emission peak value of 405 nanometers or so, belonging to blue fluorescence emission materials. The conjugate polymers can be used to make electroluminescence parts of apparatus, organic thin-film transistor and other photoelectric conversion parts of apparatus.
