The generation of unique thermosensitive fluorescent dyes via heteroaromatic Heck cross-coupling and N-pyridin-2-yl nucleophilic substitution was described. To demonstrate thermosensitive properties, the precursor was converted into carbonates or phosphates and heated at various temperatures and for various time periods. Significant changes in the fluorescence intensity and emission wavelengths, between
描述了通过杂芳族Heck交叉偶联和N-吡啶-2-基亲核取代产生独特的热敏荧光染料。为了表现出热敏特性,将前体转化为碳酸盐或磷酸盐,并在各种温度和各种时间段内加热。观察到碳酸盐和环状产物之间的荧光强度和发射波长发生了显着变化,并且证明该染料可以用作具有大斯托克斯位移(> 80 nm)的可移动荧光标记。已经证明了热敏荧光染料在寡核苷酸标记中的应用。
