Bis(indolyl)methane derivatives as highly selective colourimetric and ratiometric fluorescent molecular chemosensors for Cu2+ cations
摘要:
New probes based on bis(indolyl)methane derivatives only sense Cu2+ among other heavy and transition metal (HTM) ions through two different channels: the colourless to orange or purple colour change, that is visible to the naked eye, and a remarkable enhancement of the fluorescence along with a large red-shift in emission, in a water containing medium (CH3CN/H2O).

Micro-Cu<sub>4</sub>I<sub>4</sub>-MOF: reversible iodine adsorption and catalytic properties for tandem reaction of Friedel–Crafts alkylation of indoles with acetals
We report a convenient approach, the first of kind, to construct microscale non-metal@MOF composite catalystic host-guest system for organic tandem reaction. The reported porous Cu4I4-MOF is able to reversibly adsorb...
