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
一系列新颖的以四面体硅为中心的氰基官能化硅烷,双(4-氰基二苯基)二甲基硅烷(1),双(4-氰基二苯基)二苯基硅烷(2),三(4-氰基二苯基)甲基硅烷(3),三(4-氰基二苯基))苯基硅烷(4)和四(4-氰基二苯基)硅烷(5)已经通过Suzuki偶联反应合成。它们均显示出高的热稳定性,并且在紫罗兰色至蓝色区域中具有强烈发射的荧光。此外,1 - 5都显示出与高线性荧光淬灭响应于二苯胺(DPA)结合常数高达1.0×10 6 中号-1 在二氯甲烷溶液中的应用,证明了其在DPA检测中的潜在应用。
