A rhodamine-cyclen conjugate as a highly sensitive and selective fluorescent chemosensor for Hg(II).
A rhodamine-cyclen conjugate (1) behaves as a highly sensitive and selective fluorescent chemosensor for Hg(2+). The high emission selectivity is due to the formation of 1-Hg(2+) 1:2 complex leading to spirocycle opening of 1.
