  5-Amino-2-thiazolylpyridine N-Oxides: Synthesis and Properties

  摘要：

  5-Amino-2-thiazolylpyridine N-oxides were prepared in low to moderate yields by the oxidation of 2-pyridyl-5-aminothiazoles with m-CPBA. The molecular structures of the resulting N-oxides were unequivocally determined by X-ray analyses. The N-oxides exhibited the absorption maxima at around 415 +/- 20 nm in a CHCl3 solution, while the emission spectra were observed in the range of 505 to 604 nm. The red -shift of the emission was attributed to the methoxy groups attached to the para-position of an aromatic group on the nitrogen atom at the 5-position. The N-oxides exhibited halochromism with the addition of B(C6F5)(3). The change in absorption implied the formation of a 1:1 complex between N-oxide and B(C6F5)(3). The emission wavelengths of the N-oxides were observed at 510 +/- 25 nm in a solid state. Interestingly, one of the N-oxides having methoxy groups exhibited mechanofluorochromism. The solid-state emission of the N-oxide at 527 nm shifted to a longer wavelength (599 nm) when it was subjected to grinding.

  adopt structures that are highly twisted from planar conformations. Their orientations were tuned by the steric and/or electronic interactions of the substituents at their 2-, 4-, and 5-positions. The 5-aminothiazoles exhibited a range of fluorescent emissions, from blue to orange. Although the absorption spectra were independent of the polarity of the solvent, fluorescent emissions were influenced

  通过使衍生自仲硫代酰胺的硫代酰胺二阴离子与硫代甲酰胺反应，然后依次用碘进行氧化，可以制备一系列5-N-芳基氨基噻唑。X射线分析表明，它们采用了与平面构象高度扭曲的结构。它们的取向通过在其2-，4-和5-位上的取代基的空间和/或电子相互作用来调节。5-氨基噻唑显示出从蓝色到橙色的一系列荧光发射。尽管吸收光谱与溶剂的极性无关，但荧光发射受溶剂的极性影响：在极性更大的溶剂中，发射发生红移。根据Lippert-MaTAga图以及基态和激发态之间的偶极矩变化对这些现象进行了检验。它们还表现出固态发光，再次从蓝色到橙色。5-氨基噻唑的循环伏安法显示单电子氧化的可逆波。通过将电子给体基团引入到5-位氮原子上的苯基上，可以降低氧化的半电位。进行了DFT计算以确定HOMO和LUMO的能级。最后，TG-DTA的结果表明它们是热稳定的。进行了DFT计算以确定HOMO和LUMO的能级。最后，TG-DTA的结果表明

  Treatment of pyridyl-5-aminothiazoles (1–4) with alkyl triflates or benzyl iodide afforded the corresponding pyridinium 5-aminothiazoles (5–10), which exhibited bathochromically shifted absorption and fluorescence spectra relative to those of 1–4. Moreover, the vapochromic properties of 5 specific to halogenated solvents were examined by powder X-ray diffraction analysis. Pmma films containing 5 can

  shifts of the absorption and emission bands. DFT calculations suggested that the spectral changes arise from the protonation of the pyridyl group of the thiazoles in Et2O. Single‐crystal X‐ray diffraction analysis of a thiazole and its protonated form revealed the change of the conformation around the thiazole ring. The emission of white light was accomplished from a single fluorescent dye by adjusting
