The present invention relates to 2-functionalized and 2,7-difunctionalized carbazoles and 2,7-carbazolenevinylene oligomers and polymers. More specifically, the present invention relates to a compound of Formula (I): wherein R
1
is selected from the group consisting of H, alkyl, and aryl; and wherein R
2
and R
3
are independently selected from the group consisting of H, alkyl, formyl, hydroxymethyl, trityloxymethyl, acetonitrile, chloromethyl, methylphosphonate, methyltriphenylphosphonium and vinyl. The oligomers and polymers are used in field-effect transistors, light-emitting devices such as light-emitting diodes, and solar cells.
本发明涉及2-功能化和2,7-二功能化的咔唑和2,7-咔唑烯乙烯寡聚物和聚合物。更具体地,本发明涉及式(I)的化合物:其中,R1选自H,烷基和芳基的群;R2和R3分别选自H,烷基,甲酰基,羟甲基,三苯甲氧甲基,乙腈基,氯甲基,甲基磷酸酯,三苯基膦酸甲酯和乙烯基的群。这些寡聚物和聚合物可用于场效应晶体管、发光器件(如发光二极管)和太阳能电池。
