Three new colorimetric anion receptors 1–3 were synthesized and characterized. Among them, both 1 and 3 showed good sensitivity and selectivity for discrimination of maleatevs. fumarate or malatevs. tartrate by dramatic colour changes in DMSO or DMSO–H2O (95 : 5). Thus, both 1 and 3 can be used as optical chemosensors for recognition of maleatevs. fumarate or malatevs. tartrate anion. Besides that, the receptor 1 has also a unique colour change for recognition of either cis-aconitate or trans-aconitate in DMSO, accordingly it can be used for detection of each isomer and discrimination of cis-aconitate from trans-aconitate anion.
合成并表征了三种新的比色阴离子受体 1-3。其中,1和3对于马来酸的判别均表现出良好的敏感性和选择性。富马酸盐或马拉泰夫。酒石酸盐在 DMSO 或 DMSO–H2O (95 : 5) 中发生显着的颜色变化。因此,1和3都可以用作识别maleatevs的光学化学传感器。富马酸盐或马拉泰夫。酒石酸阴离子。除此之外,受体1还具有独特的颜色变化,可识别DMSO中的顺乌头酸或反乌头酸,因此可用于检测每种异构体以及区分顺乌头酸和反乌头酸阴离子。
