Sažetak:
The simplicity of synthesis of urea based receptors and their attractive binding site which enables multiple H-bonds for complex stabilization make urea receptors widely spread in the research field of anion recognition.1 Understanding of the structural influence on anion complexation is necessary to design the optimal receptor which should be featured with selectivity and great affinity toward specific anion.[2] Among the others, molecular rigidity, sterical constraint and conformational problems are to be solved. Recently we reported a study on anion binding ability of a series of bisureaaril derivatives focusing on the influence of structural rigidity and NH acidity on binding selectivity.[3] Herein, we present a new series of receptors with incorporated anthracene fluorophore and their binding affinities for several anions (F–, Cl–, OAc–, H2PO4–) in DMSO which were studied by UV-Vis and fluorescence spectroscopy. In addition, we investigated photocyclization of receptors in order to increase their rigidity and thereby to influence anion binding abilities and develop receptors which could be used as photochemical switches.
