The design, synthesis and physical evaluation of 1, a visible colorimetric ‘naked eye’ pyridyl based bis-amidothiourea sensor for anions, is described. This charge neutral sensor gives rise to significant changes in the absorption spectra upon interactions with several important biological anions such as AMP and ADP in 4 : 1 DMSO–H2O solution, while ATP was not detected. These colorimetric changes are due to the formation, or the combination of hydrogen bonding complexes and/or deprotonation between these anions and 1.
1 是一种 "肉眼 "可见比色的
吡啶基双脒基
硫脲阴离子传感器,本文介绍了它的设计、合成和物理评估。这种电荷中性传感器在 4 : 1
DMSO-
H2O 溶液中与几种重要的
生物阴离子(如
AMP 和
ADP)相互作用时,吸收光谱会发生显著变化,而
ATP 则检测不到。这些色度变化是由于这些阴离子与 1 之间形成或结合了氢键复合物和/或去质子化作用。
