ABSTRACT Novel symmetrical carbazole-thieno[3,4-c]pyrrole-4,6-dione-carbazoles (Carbazole-TPD-Carbazole) were designed and synthesised as donor–acceptor-donor (D-A-D) materials. The correlations between their molecular structures, differing only in the length of the symmetrical terminal linear alkyl chains attached to a carbazole-TPD-carbazole moiety in the molecular core, and their mesomorphic behaviour, transition temperatures, energy levels and band gaps were studied for a potential use of these D-A-D materials as hybrid organic semiconductors for plastic electronics applications.

高度有序液晶DAD型咔唑-TPD-咔唑的合成及介晶行为

摘要设计并合成了新型对称咔唑-噻吩并[3,4-c]吡咯-4,6-二酮-咔唑(咔唑-TPD-咔唑)作为供体-受体-供体(DAD)材料。研究了它们的分子结构之间的相关性,不同之处仅在于连接到分子核心中咔唑-TPD-咔唑部分的对称末端线性烷基链的长度,以及它们的介晶行为、转变温度、能级和带隙这些 DAD 材料作为混合有机半导体用于塑料电子应用的潜在用途。
