a) Fluorescence spectra of 1 during addition of increasing amounts of ATP. b) Changes in the monomer intensity band depending on the pH in the absence and in the presence of 10 equiv of ATP. Fluorescent enhancement observed for receptors c) 1, d) 2, e) 3, and f) 4 upon addition of increasing amounts of nucleotides and pyrophosphate as a control anion. Conditions: 0.01 mm receptor 1, λex=355 nm, 50 mm MES buffer (pH 6.2, 6 % DMSO), 25 °C. ATP—adenosine triphosphate; GTP—guanosine triphosphate; CTP—cytosine triphosphate; TTP—thymidine triphosphate; UTP—uridine triphosphate; NMP and NDP nucleotides, where N=A, T, U, C or G, correspond to mono‐ and diphosphates.
