    • The present invention provide a covered heteroaromatic ring compound whose hetero ring effectively is covered and that is suitable for electronic materials and the like. For example, following Scheme 1 below, first, a thiophene monomer unit (1T) is synthesized, and then oligomers (2T) to (16T) are synthesized by repeating oxidative polymerization. The hetero ring is not limited to thiophene, and may be furan or pyrrole, for example. Also, substituents on silicon are not limited to those in Scheme 1, and any substituents may be used. The degree of polymerization and the synthesis method are not limited to those in Scheme 1. In the compound of the present invention, π electronic conjugation effectively is kept as shown in the ultraviolet and visible absorption spectrum in FIG. 1, for example. Accordingly, the compound is useful, for example, as a research tool for clarifying electrical properties according to the degree of polymerization of oligoheterocyclic compounds, and as molecular wires that are important in molecular electronics devices.
    • 本发明提供了一种被覆盖的杂环芳族化合物,其杂环被有效地覆盖并且适用于电子材料等。 例如,按照下述方案1,首先合成噻吩单体单元(1T),然后通过重复氧化聚合合成低聚物(2T)至(16T)。 杂环不限于噻吩,例如可以是呋喃或吡咯。 此外,硅上的取代基不限于方案1中的取代基,并且可以使用任何取代基。 聚合度和合成方法不限于方案1中的那些。在本发明的化合物中,如图1中的紫外和可见吸收光谱所示,有效地保持了π电子共轭。 1,例如。 因此,该化合物可用作例如根据低聚杂环化合物的聚合度来澄清电性能的研究工具,以及作为在分子电子器件中重要的分子线。
