A far-red-fluorescent probe based on a ring-fused BODIPY core that is conjugated to a polyglycerol dendrimer is now reported. The most notable feature of this probe is its long-lasting fluorescence emission with a strikingly low level of blinking in single-molecule-imaging experiments, even in the absence of anti-fading agents such as Trolox.
