通过Biotage Isolera快速纯化液相制备色谱帮助进行带有曲轴结构的内酯桥联三联苯的合成by耐士科技

Three highly fluorescent dilactone bridged terphenyls with crankshaft architectures have been synthesized.This general class of compounds is relatively unexplored. These compounds have been characterizedby fluorescence and UVevis spectroscopy. For all three compounds, a direct correlation between the rigidity of the terphenyl system and the strength of absorption and emission of light has been observed. Preliminary studies have indicated that compounds with this architecture have the potential to be useful as pH-driven molecular switches and/or sensors with instant fluorescence attenuation at high pH values.
