摘要
以2-氨基酚和3-(二乙基氨基)苯酚为原料,经过5步反应合成了新型罗丹明类荧光探针化合物,研究发现该化合物对Ca2+具有较高的选择识别性能,并且受常见离子的干扰较小.探针的荧光强度与Ca2+浓度(2×10-6~5×10-5mol/L)呈较好的线性关系.
The novel rhodamine fluorescent chemosensor was synthesized in five steps from 2-aminophenol and 3-(diethylamino)phenol. It exhibited very strong fluorescence responses to Ca2+ and had remarkably high selectivity to Ca2+ than other metal ions. When the concentration of Ca2+ was in the range of 2 × 10-6-5 × 10-5 mol/L, there was a good linear- ity between the fluorescence intensity of the chemosensor and the concentration of Ca2+.
