(2012). A chemosensor for dihydrogenphosphate based on an oxoazamacrocycle possessing three thiourea arms. Organic & Biomolecular Chemistry, 10(28), 5379. doi: 10.1039/c2ob25498k1477-0520http://hdl.handle.net/10347/17011We report a new H-bond macrocyclic chromogenic chemosensor in organic media, H3L, which displayed drastic changes in its UV–vis spectra revealing selectivity for dihydrogenphosphate over other inorganic anions, such as acetate or fluoride. The X-ray crystal structures of the [H4L⋯NO3]·(CH3CN)4 and [H4L⋯CF3CO2]·(CH3CN)2 salt complexes are also reportedeng© The Royal Society of Chemistry 2012journal article10.1039/C2OB25498K1477-0539open access
