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.
本发明提供了一种有效覆盖杂环并适用于电子材料等的覆盖杂芳香环化合物。例如,按照下面的方案 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,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。例如,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,π 电子共轭被有效地保持。因此,本发明化合物可用作根据低聚杂环化合物的聚合度来阐明其电学性质的研究工具,也可用作在分子电子器件中非常重要的分子导线。
