Five receptors (1–5) including two macrocyclic receptors have been designed and synthesized for the recognition of dicarboxylicacids. The receptors having an NO2 group show inhibition in hydrogen bonding molecular recognition towards the dicarboxylicacid and this effect becomes more prominent in the case of macrocyclic receptors 4 and 5 in CHCl3. The binding behavior of these receptors has been studied
已经设计并合成了包括两个大环受体在内的五个受体(1-5),用于识别二元羧酸。具有NO 2基团的受体在对二羧酸的氢键分子识别中显示出抑制作用,并且在CHCl 3中的大环受体4和5的情况下,这种作用更加明显。这些受体的结合行为已经通过UV-vis,荧光和1:1 1 H NMR结合研究进行了研究。
