Novel 5,5-dioxidophenothiazine-1,9-diacetamide and -dibenzamide receptor molecules were prepared starting from commercially available and relatively cheap chemicals. The anion recognition properties of these two diamides were investigated using UV–vis spectroscopy. Chloride formed a simple hydrogen-bonded complex with the diacetamide receptor, while fluoride, acetate and dihydrogen phosphate deprotonated
从市售和相对便宜的化学品开始制备新型5,5-二氧吩噻嗪-1,9-二乙酰胺和-二苯甲酰胺受体分子。使用紫外可见光谱法研究了这两种二酰胺的阴离子识别特性。氯化物与二乙酰胺受体形成简单的氢键复合物,而氟化物,乙酸盐和磷酸二氢使两个传感器分子去质子化。在用氟化物滴定时,通过形成[HF 2 ] -发生去质子化,并且在二乙酰胺受体的情况下,在去质子化的同时发生络合。
