我们选择性地合成和表征了几种脂肪族内部亚胺异构体,它们对各种过渡金属离子表现出选择性,在溶液中的紫外-可见光谱和荧光的关-开切换有很大的位移。与不同的过渡金属的化学计量已被确定为1:1,与1,2-乙二胺二聚体显示出对汞(II)的最佳选择性。沿着配体及其金属配合物的晶体学,提出了在不同溶剂介质中的选择性和过渡金属与大环结合的不同动力学。
We have selectively synthesized and characterized several aliphatic internal imine isomers which show selectivity towards various transition metal ions with large shifts in the UV–Vis and OFF-ON switching of fluorescence in solution. The stoichiometry with different transition metals has been determined to be 1:1, with the 1,2-ethlenediamine dimer showing the best selectivity towards Hg(II). Selectivity in different solvent media and the varying kinetics of transition metal binding with the macrocycle has been presented along with the crystallography of the ligands and their metal complexes.
