title: Modified mesoporous silica nanoparticles as a reusable, selective chromogenic sensor for mercury(II) recognition.
abstract: A new tripodal receptor and a novel dyed mesoporous material are presented. The presence of thioureas conjugated with azobenzene chromophores enables the selective colorimetric detection of mercury(II) cations in THF through a remarkable colour change from yellow to deep purple.
