synthesized a thiophene hydrazone (receptor 1) that acts as a colorimetric receptor showing a reversible color switching (ON and OFF) function induced by anion and cation recognition. This remarkable color switching is based on two-input complementary IMP/INH logic functions. The (ON and OFF) process of this molecular switch is triggered by an anion (CH3COO−, C6H5COO−, HCOO−, H2PO4− or F−), while it is quenched
我们已经合成了噻吩(受体1),该噻吩可作为比色受体,表现出由阴离子和阳离子识别引起的可逆颜色转换(ON和OFF)功能。这种非凡的色彩切换基于双输入互补IMP /INH逻辑功能。该分子开关的(ON和OFF)过程通过阴离子引发的(CH 3 COO -,C 6 H ^ 5 COO - ,HCOO-,H 2 PO 4 -或F−),用任何一种方法将其淬灭M II3d(d 5 –d 10)离子以及镉II 和 汞II。一种二甲基亚砜加入任何一种上述阴离子后,受体1的溶液经历了从407到505nm的红移,而通过加入任何上述阳离子以再生在407nm的谱带而实现了关断。
