A smart "off-on" gate for the in situ detection of hydrogen sulphide with Cu(ii)-assisted europium emission
A water-soluble and emissive Eu-complex ( ) bearing a DO3A(Eu )-pyridine-aza-crown motif has been prepared and its Cu complex has been demonstrated to be a smart luminescence "off-on" gate for H S detection in water with a nano-molar detection limit (60 nM). binds to Cu ions selectively (...
