The quenchers BBQ650 and BHQ-2 exhibit significant redox blinking under common single-molecule measurement conditions. Non-fluorescent FRET acceptors can further be used to convert any dye into a photoactivatable probe.

A covalently linked photosensitizer–[Fe–Fe] hydrogenase mimic dyad is stabilized by immobilizing it into MCM-41, giving an enhanced catalytic efficiency for hydrogen production.

A picosecond temperature jump experiment reveals that phase separation in a liquid triethylamine (TEA)–water mixture started from hydrogen bond scission of TEA–water aggregates in TEA-rich regions and then in water-rich regions.

A series of bisaryl-substituted fluorescent maleimides was synthesized via the Heck arylation.

The controlled adsorption of gold colloids on dye-doped silica particles makes it possible to distinguish between a fluorescence enhancing and a quenching regime depending on the position of metal plasmon bands.

In this study photophysical characteristics of LOV-based fluorescent proteins which are essential for analytic methods as well as imaging approaches have been comparatively analyzed in detail.

The molecular basis of the photoconversion of Kaede was investigated by time-resolved spectroscopy, and the results suggest that a light-initiated cleavage mechanism (20 ps) takes place, forming the anionic red state.
