Research Abstract

In order to reveal the effect of a number of heavier elements on aromatic skeletons, we investigated the constructions of various aromatic skeletons including two silicon or silicon and phosphorus atoms. As a result, novel disilaaromatic compounds have been successfully synthesized and we have revealed their functions on the basis of element chemistry. In addition, the construction of the fundamental skeletons of polycyclic disilaaromatic compounds and heavier heterocyclic compounds has been achieved.
