The synthesis and photo-physical properties of an original bis-pyridinylpyrazine chromophore efficiently sensitising europium(III) and samarium(III) are described. The corresponding lanthanide(III) complexes display in aqueous solutions a maximum excitation wavelength which is significantly red-shifted compared to the usual terpyridine-based chelates, and a valuable luminescence brightness above 2
描述了有效地使-(III)和sa(III)敏化的原始双吡啶基吡嗪发色团的合成和光物理性质。相应的镧系元素(III)配合物在水溶液中显示出最大激发波长,该波长与通常的基于联吡啶的螯合物相比显着红移,并且在345 nm处高于2000 dm 3 mol -1 cm -1的有价值的发光亮度为用with(III)导数。还研究了三种不同生物缀合手柄的进一步功能化,并评估和比较了它们有效标记模型六肽的能力。最后,在涉及单克隆抗体的代表性标记实验中使用了最佳的可生物结合的euro(III)螯合物,相应生物结合物的发光特性仍然令人满意。
