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, pi 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.
