10-苯并[h]喹啉锂与一系列有机硅烷反应，形成中性五配位络合物。通过Sonogashira-Hagihara偶联反应，二乙炔基取代的配合物能够转化为二（芳基乙炔基）取代的配合物。电负性取代基缩短了N-Si距离，增强了配合物的荧光强度。
Reactions of 10-benzo[h]quinolyllithium with a series of organosilanes led to the formation of neutral pentacoordinate complexes. The diethynyl-substituted complex was able to be converted to di(arylethynyl)-substituted ones by the Sonogashira–Hagihara coupling reaction. Electronegative substituents shortened N–Si distances and enhanced fluorescence intensity from the complexes.
