Sažetak
Anion binding of adamantane bisurea receptors 1e4 bearing anthracene chromophores was investigated in DMSO solution by UVevis and fluorescence titrations. All derivatives form stable complexes with F¯ (K1:2z105e106 M¯ 2), AcO¯ (K1:1z103 M¯ 1), and H2PO4¯ (K1:1z103e104 M¯ 1, K1:2z105e106 M¯2). Photochemical reactivity of 1e4 in the [4pţ4p] photocyclizations was also investigated. Anthracene 1 is photochemically stable, 3 and 4 undergo reaction giving mixture of products, but 2 reacts selectively yielding only cyclic product 5. Product 5 was isolated and characterized by X-ray analysis. Cyclic receptor 5 also binds anions but forms complexes with different stability constants than its opened analogue 2. Anthracene 2 forms more stable complex with H2PO4¯, whereas cyclic receptor 5 forms the most stable complex with AcO¯ (K1:1 >106 M¯ 1).
