The nicotinamide adenine dinucleotide (NAD) derivatives NADH and NADPH are critical components of cellular energy metabolism and operate as electron carriers. A novel fluorescent ubiquinone‐rhodol derivative (UQ‐Rh) was developed as a probe for NAD(P)H. By using the artificial promoter [(η5‐C5Me5)Ir(phen)(H2O)]2+, intracellularactivation and imaging of NAD(P)H were successfully demonstrated. In contrast
utilized in various fluorescence imaging techniques. However, many existing modification strategies could not balance the performance (such as brightness, photostability, water solubility, and permeability) of fluorophores. Herein we report a general strategy to enhance the performance of donor–acceptor-type fluorophores by introducing azetidine-containing heterospirocycles to the commonly used fluorophore
off/on control, such as photoinduced electron transfer (PeT) and Förster resonance energy transfer (FRET). Here we establish a new molecular design strategy to rationally develop activatable fluorescent probes, which exhibit a fluorescence off/on change in response to target biomolecules, by controlling the twistedintramolecularchargetransfer (TICT) process. This approach was developed on the basis
