基于R，R-环己烷-1，2-二氨基支架的双双脲受体(L)与磷酸一氢离子(HPO(4)(2-))和硫酸根(SO(4)(2-))形成了罕见的2：2配合物(1)和1：1配合物(2)。用(1)H-核磁共振、UV-Vis和圆二色谱(CD)方法研究了两种阴离子的溶液结合性质。
A bis-bisurea receptor (L) based on the R,R-cyclohexane-1,2-diamino scaffold forms an uncommon 2 : 2 complex (1) with the monohydrogen phosphate ion (HPO(4)(2-)) and a 1 : 1 complex (2) with the sulfate ion (SO(4)(2-)). Solution binding properties of the two anions were studied by (1)H NMR, UV-vis, and circular dichroism (CD) methods.
