Synthesis and investigation of crown-containing anthra- and naphthoquinone properties
New derivatives of diaminodibenzocrown ethers with two chromophoric anthra- and naphthoquinone fragments in their structure are synthesized. Complexation of synthesized compounds with metal ions and ammonia is studied. The dependence of complexation processes on the type of a chromophoric system and the mutual spatial location of ionisable groups is shown.
