以[RuH 2（CO）（PPh 3）（3）]为催化剂，通过硅烷化多环芳烃（PAHs）与内炔的环化反应制备了固体荧光材料。单晶X-射线分析表明，环化通过在近位C-H断裂进行，并提供轻微应变的含硅六元环。在紫外-可见吸收和光致发光实验中，观察到环化产物相对于相应衬底的红移。
Solid-state fluorescent materials were prepared by the annulation of silylated polycyclic aromatic hydrocarbons (PAHs) with internal alkynes catalyzed by [RuH2(CO)(PPh3)(3)]. Single-crystal X-ray analysis revealed that the annulation proceeded through C-H cleavage at the peri-positions and afforded slightly strained six-membered rings containing silicon. In UV-vis absorption and photoluminescence experiments, bathochromic shifts of the annulation product as compared with those of the corresponding substrates were observed.
