摘要:
We report the synthesis of two new anion receptors of a covalently linked 1, 3,5-triarylbenzoamido-crown ether. Our results show that combined with a picrate salt they act by means of an intermolecular charge transfer process (EDA complex), as naked-eye sensors for basic anions, especially for sodium phytate in DMSO/HO2 (1:1).
