Abstract: A photoacid catalyzed O-glycosylation of alcohols with glycosyl trichloroacetimidates in the presence of commercially available phenolic photoacids, fluorescein, 4',5'-dibromo-fluorescein, and eosin Y under visible light irradiation by blue LEDs was developed. The method is operationally… read more here.

Abstract: Steady-state and time-resolved fluorescence techniques as well as quantum-mechanical calculations were used to study the photophysics and photochemistry of a newly synthesized photoacid—the phenol cyanine picolinium salt. We found that the nonradiative rate constant knr… read more here.
