首次采用拼接反应合成了一类新的硅桥π共轭化合物--喹啉稠合低聚硅杂环戊二烯。在铑催化下，两个低聚（亚甲硅烷基-亚乙炔基）之间可以以缝合方式连续形成多个碳-碳键，并且最多有五个硅杂环以醌式形式稠合。还研究了这些低聚硅杂环戊二烯的物理性质，以发现其LUMO能级的独特趋势，其随着π-共轭时间的延长而变高。
Quinoidal fused oligosiloles, a new family of silicon-bridged π-conjugated compounds, have been synthesized for the first time based on a new synthetic strategy, a stitching reaction. Multiple carbon–carbon bonds can be formed consecutively between two oligo(silylene-ethynylene)s under rhodium catalysis in a stitching manner, and up to five siloles have been fused in a quinoidal form. Physical properties of these oligosiloles have also been investigated to find a unique trend in their LUMO levels, which become higher with longer π-conjugation.
