巯基修饰ZIF-90的合成及对丙烯醛荧光传感性能研究
Synthesis of thiol-modified ZIF-90 and its fluorescent sensing performance study of acrolein
以ZIF-90为基体,通过合成后修饰法与半胱胺盐酸盐反应成功了制备巯基功能化的荧光传感ZIF-90-SH材料。结果表明,ZIF-90-SH对丙烯醛具有高灵敏度,荧光强度与ACR浓度在0.5~500 μmol/L范围内呈良好线性关系(R2=0.959),检测限低至0.49 μmol/L。此外,ZIF-90-SH在pH 5~8范围内表现出优异的荧光稳定性,且对甲醛等干扰物质具有较强的选择性与抗干扰能力。构建的基于功能化MOF的丙烯醛荧光传感探针,为实现丙烯醛的快速灵敏检测提供了新型材料与技术支撑。
In this study,ZIF-90 was used as a matrix,and through post-synthetic modification,it was successfully reacted with cysteamine hydrochloride to prepare thiol-functionalized fluorescent sensing ZIF-90-SH material.The results indicate that ZIF-90-SH exhibits high sensitivity to acrolein,with fluorescence intensity showing a good linear relationship with ACR concentration in the range of 0.5-500 μmol/L (R2=0.959),and a detection limit as low as 0.49 μmol/L.In addition,ZIF-90-SH demonstrates excellent fluorescence stability within the pH range of 5-8 and strong selectivity and anti-interference ability against interfering substances such as formaldehyde.The acrolein fluorescent sensing probe based on the functionalized MOF constructed in this study provides new materials and technical support for rapid and sensitive detection of acrolein.
