Thiazole-based chemosensor II: synthesis and fluorescence sensing of fluoride ions based on inhibition of ESIPT
摘要:
基于2-(2′-羟基苯基)-4-苯基噻唑的新型化学传感器被合成,并研究了它们的阴离子感应行为。传感器1和2对氟离子表现出选择性行为,这与它们在F−、CH3CO2 −、H2PO4 −、Cl−、Br−、I−、ClO4 −、NO3 −和HSO4 −阴离子中的吸收和发射光谱相关。传感器2在与F−相互作用时显示出颜色变化。传感器1、2和3与F−的相互作用导致紫外-可见吸收红移以及荧光发射中的较大斯托克斯位移,这 due to 由于氟离子去质子化酚质子所引起的ESIPT抑制作用。
selective, efficient, and simple method for direct transamidation of thioamides with amines, promoted by commercially available acetophenone under metal-/solvent-free conditions. The reaction tolerated a wide range of functional groups and substrates, including single- or double-thioamides, benzylamines, or alkyl/cycloalkyl-substituted aliphatic amines. The present protocol can be applied to gram-scale in
