Abstract:
Tetrathiafulvalene vinylogue (TTFV) was functionalized with two anthryl fluorophores via Cu(I)-catalyzed alkyne-azide [3 + 2] cycloaddition, forming a dianthryl-TTFV hybrid to show fluorescent turn-on sensing behaviour for Cu(2+), Fe(2+), and Cd(2+) ions in THF with remarkably low detection limit down to the sub-ppm level.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
