Abstract:
A class of novel heterocyclic compounds 1a-1c has been designed and synthesized. And our initial discovery is that these compounds can effectively recognize HSO(4)(-). With the addition of HSO(4)(-), a new energy band appears at 360-390nm in the absorption spectra. The emission spectrum (λ(ex)=328 nm) undergoes an important change in its fluorescent effect in the presence of HSO(4)(-). All available data (absorption and emission) strongly support the formation of hydrogen-bonded complexes between 1a and 1c and HSO(4)(-).
