A newly synthesized imine-based receptor (L) showed remarkable specificity toward the Hg(2+) ion in aqueous media over other metal ions. Coordination of L to Hg(2+) induces a turn-on fluorescence response. This was explained based on the restricted imine isomerization along with PET on coordination to Hg(2+). X-ray structural evidence tends to favor a C-C… CONTINUE READING
