英文摘要 | a rhodamine-azacrown derivative (2-(2-(1,4-dioxa-7,13-dithia-10-azacyclo- pentadecan-10-yl)ethyl)-3',6'-bis(diethyl amino)spiro[isoindoline-1,9'-xanthen]-3-one) responded to al3+ and fe3+ in ethanol-water solutions (20/80, v/v, ph = 7.0) and selectively responded to al3+ in acetonitrile. in addition, it bound to the cation with a simple 1:1 mode in aqueous solutions and 2:1 mode in acetonitrile. the association constants (logka) of the sensor for fe3+ and al3+ were obtained to be 6.5 and 3.6 in ethanol water, and the corresponding detection limits were calculated to be 1.2 and 8.6 x 10(-8) m, respectively, while the association constant (logka) for al3+ was 3.9 with a detection limit of 5.9 x 10(-7) m in acetonitrile under our experimental conditions. nuclear magnetic resonance and other investigations indicated that in acetonitrile the existence of the second al3+ shifted the binding location of the first al3+, which led to the spirolactam ring-open and fluorescence formation. the mechanisms for the sensor to al3+ and fe3+ in different solvents are discussed in detail.
