| Abstract: | A series of neutral cyclohexadiamine anion receptors containing nitro, phenanthroline or ruthenium(II) have been designed
and synthesized. Their u.v.–vis spectroscopy investigations reveal that the receptor bearing nitro group displays the strongest
affinities for F−, AcO−, H2PO

and can be used as an efficient detection tool for the above anions. Results indicate that the anion affinities can be enhanced
through appending nitro group and ruthenium(II) metal compared with phenanthroline moiety. |
