A reversible colorimetric and fluorescent chenosensor for trivalent metal ions (M3+), 1′-ethyl-3′,3′-dimethyl-6-nitrospiro [chromene-2,2′-indoline] spiropyran (SP) has been synthesized. The sensing ability of SP towards M3+ (Fe3+, Al3+ and Cr3+) was investigated by SEM, 1H NMR and HRMS. And the performances of SP are investigated by using of UV–vis absorption and fluorescence spectra. The SP is proved
合成了一种可逆的比色和荧光化学传感器,用于三价金属离子(M 3+),1'-乙基-3',3'-二甲基-6-硝基螺[chromene-2,2'-二氢吲哚]螺吡喃(SP)。通过SEM,1 H NMR和HRMS研究了SP对M 3+(Fe 3+,Al 3+和Cr 3+)的感测能力。利用紫外可见吸收和荧光光谱研究了SP的性能。的SP被证明是一种比色和荧光化学传感器,这是有选择性的,敏感的,良好的线性关系,检出限低,重复性好于M 3+。此外,SP还可以用作比色测试条,以检测M 3+和可重用的三态分子逻辑功能。
