A series of novel tetrahedral silicon-centered cyano functionalized silanes, bis(4-cyanodiphenyl)dimethylsilane (1), bis(4-cyanodiphenyl) diphenylsilane (2), tri(4-cyandiphenyl)methylsilane (3), tri(4-cyandiphenyl) phenylsilane (4), and tetra(4-cyandiphenyl) silane (5), have been synthesized by Suzuki coupling reactions. They all display high thermal stability, and are fluorescent with strong emission in the region of violet to blue. Furthermore, 1-5 all exhibited the linear fluorescent quenching response to diphenylamine (DPA) with the high binding constants up to 1.0 × 106 M -1 in dichloromethane solution, demonstrating the potential application in DPA detection.
