利用1，1，3，3，5，5，7，7-八乙基-s-氢化茚满-4-基（Eind）合成了在硅原子上具有2-萘基或2-芴基的π-共轭二硅烯，作为空气稳定的发射红色固体。由于3 p（pi）*（Si-Si）-2p（pi）*（碳π-电子系统）共轭的实质性贡献，在室温下，在溶液和固态中都观察到了强的α π-π * 吸收和明显的发射。
pi-Conjugated disilenes with 2-naphthyl or 2-fluorenyl groups on the silicon atoms have been synthesized as air-stable emissive red solids using the bulky 1,1,3,3,5,5,7,7-octaethyl-s-hydrindacen-4-yl (Eind) groups. The strong a pi-pi* absorptions and distinct emission at room temperature, both in solution and in the solid state, have been observed due to the substantial contribution of the 3p(pi)*(Si-Si)-2p(pi)*(carbon pi-electron system) conjugation.
