heteroatoms (O and N atoms) are incorporated into the thienylene vinylene moieties to tune the electronic properties and intermolecular interactions. Third, the alkyl side chains are optimized to tune the solubility and self‐assembly properties. As a consequence, a remarkable thin film transistor performance is obtained. The very high hole mobility of 3.22 cm2 V−1 s−1 is achieved for the p‐type polymer, PSNVT‐DTC8
由亚芳基亚乙烯基和二噻吩-噻二唑并苯并三唑(SN)单元组成的高迁移率半导体聚合物是通过三种强大的设计策略开发的,即骨架工程,杂原子取代和侧链工程。首先,从四噻吩-SN共聚物开始,将亚乙烯基间隔基插入四噻吩单元中,以构建高度平面的骨架。其次,将杂原子(O和N原子)结合到亚硫撑亚乙烯基部分中,以调节电子性能和分子间相互作用。第三,优化烷基侧链以调节溶解度和自组装性能。结果,获得了显着的薄膜晶体管性能。3.22 cm 2 V -1 s的极高空穴迁移率p型聚合物PSNVT-DTC8达到-1,这是基于苯并双噻二唑及其类似物的聚合物的最高报道值。此外,杂原子取代有效地改变了聚合物的电荷极性,就像N原子取代的PSNVT z-DTC16表现出n型主要双极性性质,电子迁移率为0.16 cm 2 V -1 s -1一样。使用掠入射广角X射线散射和原子力显微镜的进一步研究表明,具有强π-π相互作用和合适的聚合物堆积方向的聚合物薄膜具有很高的结晶度。
Thiazolylmethylenetriphenylphosporane and its benzo derivative: stable and practical wittig reagents for the synthesis of vinylthiazoles and vinylbenzo
is a stable yet quite reactive Wittig-type reagent which upon reaction with various aldehydes affords vinylthiazoles, mainly or exclusively as -isomers, in very good yields. Also the benzothiazolyl phosphorane derivative, unlike a literature report, prove to react with aldehydes. Vinylthiazoles subjected to formyl deblocking from thiazole nucleous afford two-carbon homologated satured aldehydes. As
The invention relates to organic electroluminescent devices comprising organic compounds with a double or triple bond, to which at least one aromatic ring is bonded, as emitter compounds. The invention also relates to possible uses of said devices.
