A new ‘naked-eye’ quinoline-based ‘reactive’ ratiometric fluorescent probe was prepared. The reactive stoichiometry of the probe with Hg2+ ion was 2:1. The probe exhibited high selectivity towards Hg2+ ion to other metal ions with a 410-fold increase in absorbance intensity ratio (A402/A340) in aqueoussolution over a wide-range pH value (2–12), accompanied by a resonance color change from colorless
制备了一种新的基于“裸眼”喹啉的“反应性”比例荧光探针。探针与Hg 2+离子的反应化学计量为2:1。该探针对Hg 2+离子具有比其他金属离子高的选择性,在宽范围的pH值(2-12)范围内,水溶液中的吸收强度比(A 402 / A 340)增加410倍,并伴随着共振色从肉眼可见的无色变为浅黄色。
Synthesis and photophysical properties of new styrylquinoline-containing polymers
novel polymers with styrylquinoline moiety and different substituents units have been successfully synthesized by radical polymerization. Styrylquinoline polymers were obtained by a three-step synthetic approach. This includes the condensation, preparation of a methacrylic monomers and their polymerization. The synthesized polymers are soluble in common organic solvents. Their photophysical and photochemical
