摘　　要：采用FeCl3法合成了聚3-己基噻吩(P3HT)和聚3-十二烷基噻吩(P3DDT),用GPC法和1H-NMR法对结构进行了表征,用Tg法研究了它们的热稳定性,并对溶液和薄膜的紫外-可见吸收性能、光致发光性能和能隙进行了对比研究。P3HT和P3DDT溶液最大吸收峰分别在420nm和413nm,相应的发射峰分别为602nm和573nm;薄膜的最大吸收峰分别为430nm和415nm,相应的发射峰分别为622nm和589nm,它们的禁带宽度分别为1.9eV和2.2eV。P3HT and P3DDT were synthesized by the method of FeCl3. Chemical structures were characterized by gel permeation chromatography （GPC） and ^1 H- NMR, thermal stability was studied by Tg. The absorption, fluorescence properties and the band gap of them in chloroform solutions and their spin-coating films were studied. The maximum Uv-vis wavelength of P3HT and P3DDT in chloroform solutions were 420 nm and 413 nm, respectively, and their corresponding emitted wavelengths are 602 nm and 573 nm. The maximum Uv-vis wavelength of their spin-coating films are 430 nm and 415 nm respectively, and their corresponding emitted wavelengths are 622 nm and 589 nm. Band gap data are 1.9 eV and 2.2 eV, respectively.
