The fluorescent lifetimes of the BODIPY–BODIPY dyad appear to correlate with the viscosity of the media, thus making this rotor a suitable small molecule viscometer. A symmetrical BODIPY–BODIPY dyad with a diyne linker was prepared in two steps; the lifetime decay of this rotor appeared to correlate...

Description
Summary:The fluorescent lifetimes of the BODIPY–BODIPY dyad appear to correlate with the viscosity of the media, thus making this rotor a suitable small molecule viscometer. A symmetrical BODIPY–BODIPY dyad with a diyne linker was prepared in two steps; the lifetime decay of this rotor appeared to correlate with the viscosity of the media, thus making this dyad a suitable small molecule viscometer for molecular solvents. The potential of using the rotor to probe the viscosity of ionic liquids was also investigated.
