Here we report our recent result of a new semiconductor material, which has an asymmetric structure. The synthesized molecules consist of anthracene and thiophene connected by bridged ethylene and substituted with hexyl or dodecyl groups as pendants. The semiconductors were synthesized using a McMurry coupling reaction between anthracene-2-carbaldehyde and corresponding 5-hexyl(or dodecyl)thiophene-2-carbaldehyde. A first investigation of synthesized asymmetry AVHT (9a) and AVDT (9b) for the physical properties showed that they have high oxidation potential and thermal stability. The devices prepared by using AVHT (9a) and AVDT (9b) showed the mobility of $2.6\times}10^-2}cm^2/Vs$ and $4.4\times}10^-3}cm^2/Vs$, respectively, in solution processed OTFTs.
在此,我们报告了一种具有不对称结构的新型半导体材料的最新研究成果。合成的分子由蒽和噻吩组成,通过桥接乙烯连接,并以己基或十二烷基作为取代基。这些半导体是通过蒽-2-甲醛和相应的 5-己基(或十二烷基)噻吩-2-甲醛之间的麦克默里偶联反应合成的。对合成的不对称 AVHT(9a)和 AVDT(9b)物理性质的初步研究表明,它们具有较高的氧化电位和热稳定性。使用 AVHT (9a) 和 AVDT (9b) 制备的器件在溶液处理 OTFT 中的迁移率分别为$2.6\times}10^-2}cm^2/Vs$和$4.4\times}10^-3}cm^2/Vs$。
