咔唑-呋喃-噻吩以及吲哚-呋喃-噻吩齐聚物的合成

Synthesis of Carbazole-Furan—Thiophene and Indole Furan—Thiophene Oligomers

五氟苯和五氛溴苯是公认的代表性的含氟化合物,可以通过多种反应与其它化合物相连接。N-芳化杂环化合物例如咔畦和吲哚是具有空穴传输性能、在紫外光范围有很强的吸收并且具有发可贵的蓝光等特性。以咔唑为侧基的非共轭类聚合物具有很好的光学性能和空穴传输性能。呋喃噻吩齐聚物具有优异的性质。该文发展了合成咔唑-呋喃-噻吩以及吲哚-呋喃-噻吩齐聚物的方法。以自制的五氨苯代吲哚和五氟苯代咔唑为起始原料,与硼该剂反应分别制备相应的硼酸酯。通过溴封端的噻吩-氟代呋喃-噻吩中间体与硼酸酯反应制备咔唑-呋喃噻吩以及吲哚-呋喃-噻吩齐聚物。

Pentafluorophenyl and pentafluoroethyl bromobenzene is recognized as a class of fluorochemical representative, can be connected to other compounds by a variety of reactions.N-arylation heterocyclic compounds such as carbazole and indole is a hole transport properties in the UV range and has a strong absorption of valuable blue light and other features.Carbazole is a side group of non-conjugated polymer with good optical properties and hole transport properties. Furan thiophene oligomers have excellent properties. This paper developed a new method for the synthesis of carbazole-furan-thiophene and indole-furan-thiophene oligomer.Pentafluorophenyl substituting indole and carbazole as starting material, under the action of boron, the corresponding boronate ester were synthesized. Bromine-capped thiophene- fluoro-furan-thiophene intermediate was produced, and then it was reacted with boric acid esters,prepared carbazole-furan thiophene and indole-furan-thiophene oligomers.
