| 摘要: 在羟基冠醚的羟基上直接引人生色基以制生色冠醚,尚未见报道。我们用2-羟基-5-硝基苄氯(2)作为生色剂,在氢化钠作用下与6-羟基-2,3,9,10-二苯并-16-冠-5(1)反应,合成了6-[(2′-羟基-5′-硝基苯基)甲氧基]-2,3,9,10-二苯并-16-冠-5(3)。 |

| Abstract: A new chromogenic crown ether 3 was synthesized by the reaction of the hydroxy crown ether 1 with the chromogenic agent 2 and NaH in THF/DMF. The electronic spectra of 3 and its tetramethylammonium salt (3') in methanol have shown that no or less reaction took place with various alkali metal salts and magnesium salt, but selective coloration was apparently observed when they reacted with Ca2+, Sr2+ and Ba2+ salts as shown by △λmax-34, -19 and -14 nm respectively. In this paper, the solvent effect and anionic effect of coordination have also been examined and the probable structures of the complexes were described. |
